Direction DOC1906666
This DICOM Conformance Statement documents the DICOM Conformance Statement and Technical
Specification required interoperating with the GEHC network interface.
The GEHC Conformance Statement, contained in this document, also specifies the Lower Layer
communications, which it supports (e.g., TCP/IP). However, the Technical Specifications are defined
in the DICOM Part 8 standard.
For more information regarding DICOM, copies of the Standard may be obtained on the Internet at
http://medical.nema.org. Comments on the Standard may be addressed to:

Intended Audience
The reader of this document is concerned with software design and/or system integration
issues. It is assumed that the reader of this document is familiar with the DICOM Standard
and with the terminology and concepts, which are used in that Standard.
1.4
Scope and Field of Application
It is the intent of this document to provide an unambiguous specification for GEHC implementations.
This specification, called a Conformance Statement, includes a DICOM Conformance Statement and
is necessary to ensure proper processing and interpretation of GEHC medical data exchanged using
DICOM. The GEHC Conformance Statements are available to the public.
The reader of this DICOM Conformance Statement should be aware that different GEHC devices are
capable of using different Information Object Definitions. For example, a GEHC CT Scanner may
send images using the CT Information Object, MR Information Object, Secondary Capture Object, etc.
Included in this DICOM Conformance Statement are the Module Definitions, which define all data
elements, used by this GEHC implementation. If the user encounters unspecified private data
elements while parsing a GEHC Data Set, the user is well advised to ignore those data elements (per
the DICOM standard). Unspecified private data element information is subject to change without
notice. If, however, the device is acting as a "full fidelity storage device", it should retain and retransmit all of the private data elements which are sent by GEHC devices.

REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
Important Remarks
The use of these Conformance Statements, in conjunction with the DICOM Standards, is intended to
facilitate communication with GE imaging equipment. However, by itself, it is not sufficient to
insure that inter-operation will be successful. The user (or user’s agent) needs to proceed with
caution and address at least four issues:
Integration
The integration of any device into an overall system of interconnected devices goes beyond
the scope of standards (DICOM), and of this introduction and associated Conformance
Statements when interoperability with non-GE equipment is desired. The responsibility to
analyze the applications requirements and to design a solution that integrates GE imaging
equipment with non-GE systems is the user’s responsibility and should not be
underestimated. The user is strongly advised to ensure that such integration analysis is
correctly performed.
Validation
Testing the complete range of possible interactions between any GE device and non-GE
devices, before the connection is declared operational, should not be overlooked. Therefore,
the user should ensure that any non-GE provider accepts full responsibility for all validation
required for their connection with GE devices. This includes the accuracy of the image data
once it has crossed the interface between the GE imaging equipment and the non-GE device
and the stability of the image data for the intended applications.
Such a validation is required before any clinical use (diagnosis and/or treatment) is
performed. It applies when images acquired on GE imaging equipment are
processed/displayed on a non-GE device, as well as when images acquired on non-GE
equipment is processed/displayed on a GE console or workstation.
Future Evolution
GE understands that the DICOM Standard will evolve to meet the user’s growing
requirements. GE is actively involved in the development of the DICOM Standard. DICOM will
incorporate new features and technologies and GE may follow the evolution of the Standard.
Evolution of the Standard may require changes to devices that have implemented DICOM. In
addition, GE reserves the right to discontinue or make changes to the support of
communications features (on its products) reflected on by these DICOM Conformance
Statements. The user should ensure that any non-GE provider, which connects with GE
devices, also plans future evolution of the DICOM standard. Failures to do so will likely result in
the loss of function and/or connectivity as the DICOM Standard changes and GE products are
enhanced to support these changes.
Interaction
It is the sole responsibility of the non-GE provider to ensure that communications with the
interfaced equipment does not cause degradation of GE imaging equipment performance
and/or function.

Definitions
Informal definitions are provided for the following terms used in this Conformance Statement. The
DICOM Standard is the authoritative source for formal definitions of these terms.
Abstract Syntax – the information agreed to be exchanged between applications, generally
equivalent to a Service/Object Pair (SOP) Class. Examples: Verification SOP Class, Modality Worklist
Information Model Find SOP Class, Computed Radiography Image Storage SOP Class.
Application Entity (AE) – an end point of a DICOM information exchange, including the DICOM
network or media interface software; i.e., the software that sends or receives DICOM information
objects or messages. A single device may have multiple Application Entities.
Application Entity Title – the externally known name of an Application Entity, used to identify a
DICOM application to other DICOM applications on the network.
Application Context – the specification of the type of communication used between Application
Entities. Example: DICOM network protocol.
Association – a network communication channel set up between Application Entities.
Attribute – – a unit of information in an object definition; a data element identified by a tag. The
information may be a complex data structure (Sequence), itself composed of lower level data
elements. Examples: Patient ID (0010,0020), Accession Number (0008,0050), Photometric
Interpretation (0028,0004), Procedure Code Sequence (0008,1032).
Information Object Definition (IOD) – the specified set of Attributes that comprise a type of data
object; does not represent a specific instance of the data object, but rather a class of similar data
objects that have the same properties. The Attributes may be specified as Mandatory (Type 1),
Required but possibly unknown (Type 2), or Optional (Type 3), and there may be conditions associated
with the use of an Attribute (Types 1C and 2C). Examples: MR Image IOD, CT Image IOD, Print Job IOD.
Joint Photographic Experts Group (JPEG) – a set of standardized image compression techniques,
available for use by DICOM applications.
Media Application Profile – the specification of DICOM information objects and encoding exchanged
on removable media (e.g., CDs)
Module – a set of Attributes within an Information Object Definition that are logically related to each
other. Example: Patient Module includes Patient Name, Patient ID, Patient Birth Date, and Patient Sex.
Negotiation – first phase of Association establishment that allows Application Entities to agree on
the types of data to be exchanged and how that data will be encoded.

GE HEALTHCARE
DIRECTION DOC1906666, REV 1
REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
Presentation Context – the set of DICOM network services used over an Association, as negotiated
between Application Entities; includes Abstract Syntaxes and Transfer Syntaxes.
Protocol Data Unit (PDU) – a packet (piece) of a DICOM message sent across the network. Devices
must specify the maximum size packet they can receive for DICOM messages.
Security Profile – a set of mechanisms, such as encryption, user authentication, or digital signatures,
used by an Application Entity to ensure confidentiality, integrity, and/or availability of exchanged
DICOM data
Service Class Provider (SCP) – role of an Application Entity that provides a DICOM network service;
typically, a server that performs operations requested by another Application Entity (Service Class
User). Examples: Picture Archiving and Communication System (image storage SCP, and image
query/retrieve SCP), Radiology Information System (modality worklist SCP).
Service Class User (SCU) – role of an Application Entity that uses a DICOM network service; typically,
a client. Examples: imaging modality (image storage SCU, and modality worklist SCU), imaging
workstation (image query/retrieve SCU)
Service/Object Pair (SOP) Class – the specification of the network or media transfer (service) of a
particular type of data (object); the fundamental unit of DICOM interoperability specification.
Examples: Ultrasound Image Storage Service, Basic Grayscale Print Management.
Service/Object Pair (SOP) Instance – information object; a specific occurrence of information
exchanged in a SOP Class. Examples: a specific x-ray image.
Tag – a 32-bit identifier for a data element, represented as a pair of four digit hexadecimal numbers,
the “group” and the “element”. If the “group” number is odd, the tag is for a private (manufacturerspecific) data element. Examples: (0010,0020) [Patient ID], (07FE,0010) [Pixel Data], (0019,0210)
[private data element]
Transfer Syntax – the encoding used for exchange of DICOM information objects and messages.
Examples: JPEG compressed (images), little endian explicit value representation.
Unique Identifier (UID) – a globally unique “dotted decimal” string that identifies a specific object or
a class of objects; an ISO-8824 Object Identifier. Examples: Study Instance UID, SOP Class UID, SOP
Instance UID.
Value Representation (VR) – the format type of an individual DICOM data element, such as text, an
integer, a person’s name, or a code. DICOM information objects can be transmitted with either
explicit identification of the type of each data element (Explicit VR), or without explicit identification
(Implicit VR); with Implicit VR, the receiving application must use a DICOM data dictionary to look up
the format of each data

DIRECTION DOC1906666, REV 1
REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
There are several Real-World Activities that will cause the DICOM Server Application Entity (DICOM
Server AE) to initiate a DICOM association to a remote DICOM Application Entity. Illustration 2.0 above
shows basic Real-World Activities. In addition, Sections 3, 4, 5, 6, and 7 cover Media Storage, Print,
Modality Worklist, Performed Procedure Step, and Storage Commit in more detail.
The following paragraphs describe the Real-World Activities of Illustration 2.0:
1. Push Images
This Real-World Activity consists of an operator selecting one or more studies, series, or images
in the local database browser. The operator then clicks on the destination button in the
network panel at the bottom of the local database browser.
2. Manual Query
The operator queries one or a set of remote DICOM databases to obtain a list of data at
Study/Series/Image level by clicking on the icon that represents the wanted remote DICOM AE.
3. Manual Retrieve
This Real-World activity will be available once the Manual Query activity is performed. The
operator can now select one or more studies (series or images) and ask the DICOM Server AE to
retrieve the selected image(s) from the Remote DICOM AE by clicking on the “Local DB” button
at the bottom of the local database browser.
4. Verify Connectivity (DICOM Ping)
This Real-World activity consists of an operator selecting a Remote DICOM AE from the
“Network Configuration” window and clicking on “Ping” on the right side-bar. This is to check
the status of the selected remote DICOM AE.
5. Remote Archive
This Real-World activity consists of an operator choosing a remote DICOM AE that supports
Storage Commitment as provider from the archive panel at the bottom of the local database
browser. The operator chooses the exam or series in the local database browser and clicks on
the archival destination from the archive list at the bottom of the local database browser.
The Commitment request for the transferred image instances is sent after the complete image
transfer. The Commitment response can come on same association or on a different
association. Refer to Section 5 for details on the Storage Commitment implementation.
6. Modality Worklist Query
The operator or the system initiates a modality worklist query to the modality worklist SCP with
a given set of query parameters. The modality worklist SCP returns responses matching the
query parameters. Worklist items from the returned worklist query responses are presented to
the user. The user then chooses the desired worklist item and begins the image acquisition
process.
7. Modality Performed Procedure Step Notification
When the user begins the image acquisition process and generates the first image, the DICOM
25 of 181
GE HEALTHCARE
DIRECTION DOC1906666, REV 1
REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
SERVER AE sends N-CREATE message to the configured MPPS SCP to indicate that the image
acquisition process has been started for the requested procedure.
The operator can close the acquisition session either by completing the acquisition process or
discontinuing the ongoing scan. On closing the acquisition session, the DICOM SERVER AE
sends N-SET message to the configured MPPS SCP to indicate the acquisition state of the
requested procedure, with appropriate MPPS status (COMPLETED/DISCONTINUED).
8. Print
The Film Composer allows the operator to select printers and it also allows the user to drag and
drop the images (from viewer application) into the film. When user presses the "Print" Button,
the DICOM SERVER AE tries to establish the association with requested printer and sends the
images for printing.
9. Receive Images
When remote DICOM hosts send DICOM images to DICOM SERVER AE, images are installed in
the local database. The browser displays the content of the local database.
10. Image Installation
The DICOM Server AE will perform this Real-World activity after the remote AE sends an image
to the GEHC CT product.
11. Receive Verification request
No operator action is required to respond to a verification message. The Real-World Activity
associated with the verification request is to send a C-ECHO response message with a status of
“success” to the requesting AE.
12. Search Local Database
For this operation, a remote DICOM AE asks to obtain the list of data at Study/Series/Image
level. Once a Query request is received, the DICOM Server AE will search the local database for
all entries that match the keys requested by the Remote DICOM AE and send back the list of
matches.
13. Move Images
For this operation, a remote DICOM AE asks to send data at Study/Series/Image level from the
local AE to another DICOM Remote AE. The Remote DICOM AE shall be declared locally on the
system. The declaration of remote DICOM AE is done through a configuration tool.
14. Listen to remote Storage Commitment SCP
The DICOM SERVER AE is indefinitely listening for association requests. No operator action is
required to receive a Storage Commitment notofication (N-EVENT-REPORT)
2.2.2 Functional Definition of AE’s
DICOM Server Application Entity initiates the following operations:
Initiate an association to a Remote AE for the purpose of sending images to the Remote AE.
Remote AE accepts the presentation context applicable to the image(s) being sent, the DICOM
26 of 181
GE HEALTHCARE
DIRECTION DOC1906666, REV 1
REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
Server AE will send the image(s) to the receiving Remote AE by invoking the C-STORE-RQ
operation for each image on the same association.
Initiate an association to a Remote AE for the purpose of committing images previously sent
successfully to the Remote AE for the purpose of the remote AE to commit to the storage of
those images. If the Remote AE accepts the presentation context, a storage commitment will be
established with the Remote AE with the DICOM Server AE sending the N-ACTION Request. The
Remote AE completes the commitment by sending the N-EVENT REPORT. The DICOM Server AE
updates the archive flag in the image browser for successful instances.
Initiate an association with a Remote AE to query for images on the remote host. A Study-Root
Study-Level C-FIND-RQ request will be sent to the Remote AE once an association has been
established. Once all the responses have been received, the operator needs to select an exam in
the local database browser, on selection of the exam the DICOM Server AE will issue a SeriesLevel C-FIND-RQ request to get the series for a study in the list. Similarly the Image-Level C-FINDRQ will be issued for the series selected from the series list.
Send a C-MOVE-RQ request to a Remote AE for retrieve of images after successful establishment.
The DICOM Server AE’s Storage SCP will receive the images over a separate association.
Initiate an association with a Remote AE to verify its status with a C-ECHO-RQ. The Remote AE
will report its status in a C-ECHO-RSP
Initiate an association with a Remote AE to query for and display DICOM modality worklist
information. Once the remote AE accepts the presentation context, CT system will issue a
modality worklist query request using the C-FIND service
Initiate an association with a Remote AE to create and update DICOM Modality Performed
Procedure Step SOP instance in the remote AE. Once the remote AE accepts the presentation
context, SOP instance is created using N-CREATE service and updated using N-SET service.
Initiates as association with a remote printer for printing the images. If the Remote AE accepts
the presentation context applicable to the print job, CT system will send the print job to the
receiving remote AE.
The DICOM Server AE waits for association requests from Remote AEs that wish to perform the
following operations:
Verification: If a C-ECHO-RQ message is received, the DICOM Server AE will send back a C-ECHORSP message with a status of “success”.
Image Storage: If a C-STORE-RQ message is received, the DICOM Server AE will receive the
image and try to update the local database. If the image is stored successfully on storage media
and the database updated a status of “success” will be returned in a C-STORE-RSP message.
Query: If a C-FIND-RQ message is received the DICOM Server AE will search the database for the
requested attributes and send back a C-FIND-RSP message containing a match and a status of
27 of 181
GE HEALTHCARE
DIRECTION DOC1906666, REV 1
REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
“pending”. After all matching records have been sent, a status of “success” will be returned in a
C-FIND-RSP message. The Remote AE can terminate the query by sending a C-CANCEL-FIND-RQ
message.
Retrieve: If a C-MOVE-RQ message is received the DICOM Server AE will look up its list of
configured Remote AEs for the Destination AE. If the Destination AE is configured, the DICOM
Server AE will open a new association to the Destination AE and use C-STORE-RQ to send the
image(s). The DICOM Server AE will send a C-MOVE-RSP message with a status of “pending” after
every five images are sent. When all images are sent or if DICOM Server AE receives a C-CANCELMOVE-RQ a final C-STORE-RSP will be sent back with an appropriate status.
Storage Commitment Response: If a N-EVENT-REPORT request is received from the Remote
Storage Commitment SCP the DICOM Server AE will update the Archive flag information for
successful instances.

SOP Specific Conformance Statement for all storage SOP Classes
This implementation can perform multiple C-STORE operations over a single association.
Upon receiving a C-STORE confirmation containing a successful status, this implementation will
perform the next C-STORE operation. The association will be maintained if possible.
Upon receiving a C-STORE confirmation containing a Refused status, this implementation will
terminate the association.
Upon receiving a C-STORE confirmation containing any status that is not Success or Warning, this
implementation will consider the current request to be a failure and will terminate the association
except if the C-STORE is invoked from a C-MOVE SCP. In this case it will continue to attempt to send
the remaining images in the request on the same association.

Each C-STORE operation supports an “Association Timer”. This timer starts when the association
request is sent or received and stops when the association is established. The time-out is
configurable in network-cfg.xml file as StoreAssociationTimeout. Default is 60 seconds.
Each C-STORE operation also supports an “Operation Inactivity Timer”. This time-out starts once the
first C-STORE request has been issued (on association) or received and is reset each time a C-STORE
response has been received or when subsequent C-STORES are sent. This time-out is configurable
in networkcfg.xml file as StoreResponseTimeout. Default is 5 minutes.
If any of the two timers mentioned above expires, the connection is closed and the operation in
progress is considered failed.
Note: The time-outs are configurable.
When DICOM Server AE initiates an association to issue a C-STORE, the image will be transmitted by
the DICOM Server AE with the same elements as was originally received or created locally.

2.3.1.2.2 Real World Activity: Manual Query
2.3.1.2.2.1 Associated Real-World Activity
The operator must select the Remote DICOM AE from the “Source” pull-down on the local database
browser and select the hostname of the source from where the images are to be retrieved.
Provided that the operator had set "Custom search" to "Off" when setting the Remote host
parameters, the “Query” operation will cause the DICOM Server AE to initiate an association (with
zero length Patient name, Patient id, Study date, Accession number, and Study id) to the selected
Remote AE when the “Hostname” entry is selected from the “Source” pull-down menu.
Otherwise, if the operator had set "Custom search" to "On" when setting the Remote host parameters,
the “Query” operation will cause a Customize search parameters menu to appear. The operator can

enter values for Patient name, Patient id, Study date, Accession number, and Study id. Not entering a
value means match on any value for that field. Patient name will match on any patient name that
contains what the operator entered. Patient id, Study id, and Accession number will match on what
the operator enters.
For Study date, the operator selects a range type from the "Exam Date" pull down menu, where the
choices are “Equals“, “Before“, “Between“, or “After“. Once a range type is selected, the correct
number of fields appears and the operator enters dates into those fields. Once the desired
parameters are entered the operator chooses "OK" and that will cause the DICOM Server AE to
initiate an association to the selected Remote AE.
Once a list of Study/Series/Image is retrieved, the operator can invoke the “Pull” operation by clicking
on the “Local DB” button at the bottom of the local database browser.

2.3.1.2.2.2.1 SOP Specific Conformance Statement for C-FIND SCU
After the Query operation is initiated, the DICOM Server AE will perform a study-root C-FIND-RQ
request at each of the three levels (Study, Series, and Image) in succession.
The Initial Study-Level request will ask for all studies in the Remote database that match the user
specified Patient name, Patient Id, Study ID, Accession number, and Study Date. Zero length data in
any of those fields means match on any value. Zero length data is the default value if the user does
not specify a value.
The user specified Patient name will come surrounded by single asterisks (asterisk is a wild card that
matches any number of characters).
Caret (“^”) character cannot be used as a separator of Last name and First name.
The Study date is a range of dates where a date is exactly 8 characters long and the format of the
35 of 181

range is:
"" is any date,
"yyyymmdd-" is any date on or after that year/month/day,
"-yyyymmdd" is any date on or before that year/month/day,
"yyyymmdd-yyyymmdd" is any date on or between those dates,
"yyyymmdd" is only on that date.
The C-FIND SCU will not perform any extended negotiation and so will only perform hierarchical
query. Relational Queries are not supported.
Each C-FIND SCU operation supports an “Association Timer” and “Operation Inactivity Timer” using
QueryAssociationTimeout and QueryResponseTimeout, in network-cfg.xml configuration file.
Default values are 30 seconds, 5 minutes respectively.
The user can cancel the current C-FIND request by changing the source listing to Local DB or any
other remote host. If a query operation is in progress, the DICOM SERVER AE will issue a C-FINDCANCEL message to the remote AE to discontinue the ongoing C-FIND operation.
If a “Cancel” or “Refused” status is returned from the Remote AE the association is closed and the
operation terminated.
The user can cancel the C-FIND request by moving to another network node or clicking on the local
database.
The DICOM Server AE will parse each matching C-FIND-RSP reply and ignore the entries that do not
contain a valid DICOM data stream. No VR validation is performed which means that syntax errors
will be ignored. Tables 2.3.1.2.2.2.1-1 - 2.3.1.2.2.2.1-3 shows the various fields that are requested at
the Study, Series, and Image levels of the C-FIND request.
Query results are filtered based on the Modality field. Only CT/MR Screen Save images are supported.

2.3.1.2.3.2.1 SOP Specific Conformance Statement for C-MOVE SCU
When the operator starts a Move operation at any level (Study, Series, Image) the DICOM Server AE
will initiate a C-MOVE-RQ request with UIDs at the appropriate level (Study, Series, Image) to the
Remote AE with the DICOM Server AE as the Destination AE. The Storage SCP (“Receive Images”) will
handle the incoming images as described in section 2.3.1.3.1.
C-MOVE supports list of Studies (through list of Study UIDs), list of Series (through list of Series UIDs)
and list of Images (through list of Instances UIDs).
Each C-MOVE SCU operation supports an “Association Timer” and “Operation Inactivity Timer” with
time out values of 30 seconds and 15 seconds respectively.
If the C-MOVE SCU receives a status different from success (0x0000) or pending (0xFF00) during the
association, the DICOM SERVER AE will release the association. This information will be logged in the
system log files and the network queue will be updated accordingly.
During Manual Retrieve, the DICOM SERVER AE is able to generate a C-MOVE-CANCEL if the operator
Pauses or Deletes the retrieve job.
When receiving a Cancel request response (0xFE00), the DICOM SERVER AE will release the
association. This information will be logged in the system log files and the network queue will be
updated accordingly.

2.3.1.2.5 Real-World Activity: Remote Archive
2.3.1.2.5.1
Associated Real World Activity: “Choose Archive Save Option”
The operator must first set remote hosts from Network Configuration from “Tools“ pull-down menu. If
the remote node is already present, select one remote host, click “Edit“ on the right side-bar and
make a check on “Archive Node” check box. If the remote host is not present, add the remote host
with check on “Archive Node” check box.
Note: The remote node should be a Storage Commitment SCP. STC AE Title can be different from
STORE AE title. The user selects the exam/series to be committed and click on the archival
destination from the archive list at the bottom of the local database browser.
All the images currently in the selected exam/series will be sent to the selected remote archive node
(which is also the Storage commitment SCP) using DICOM C-STORE operations. Once all the images
are transferred the commitment request will be sent on a separate association.
2.3.1.2.5.2

The images in the selected exam/series are sent to the remote commitment provider entity using
DICOM C-STORE operations. If there are any failures in the image transfers the Storage
Commitment request will not be sent. The corresponding job will be marked as failed and user will
be notified of the status of job.
If all the images are successfully transferred then the commitment request will be sent on a
different association with the list of SOP instances.
If the N-Action request fails, the job will be marked as failed otherwise following sequence of
actions will take place.
The SCU waits for N_ACTION response from the provider on the same association for a configurable
amount of time. Default time-out is 600 seconds. If it does not receive N_ACTION response during
this time it closes the association and marks the job as failed.
If the received N-ACTION Response from the Storage Commitment Provider has a success status,
the DICOM SERVER AE waits 10 seconds for an N-EVENT-REPORT on the same association. This
time-out is not configurable. If the N-EVENT-REPORT request is not received in this time, it closes the
association and changes the Job state to ”Waiting” indicating the job is waiting for the response
from commitment provider.
The DICOM SERVER AE can receive N-EVENT-REPORT from the Storage Commitment Provider at any
time (See section 2.3.1.3.5 - Real-World Activity: Listen to remote Storage Commitment SCP”).
A New transaction UID will be created for each retry by user. The old transaction uid is not

2.3.1.2.6 Real-World Activity: Modality Worklist Query
2.3.1.2.6.1 Associated Real-World Activity
The operator of the system initiates a query for a modality worklist by either opening the Schedule
screen or by opening the Schedule screen and pressing the Update button. The choice of which of
these two behaviors occurs is user configurable. The Worklist Server will then initiate an association
with the remote AE in order to query for the worklist
A user can configure a number of parameters that directly control the worklist query request. The user
can request worklist items that are intended for the scanner the user is working at, all items that apply
to the modality of the scanner the user is working at or all worklist items available. These selections
and their effects on worklist query parameters are given below:

The scheduled dates of procedures of interest can be specified for query by selecting a specific date
range. The date ranges available are Today, Days Before Today, Days After Today and All Days. These
selections and their effects on worklist query parameters are given below:
Today:
Scheduled Procedure Step Start Date (0040,0002) - set to
YYYYMMDD, where this date is the current date.
Days Before Today and Scheduled Procedure Step Start Date (0040,0002) - set to

2.3.1.2.7 Real-World Activity: Modality Performed Procedure Step Notification
The PPS Server AE is implemented as an application process on the scanner host computer. It runs as
a daemon serving requests from other applications to send the PPS information to the remote AE and
return the results to the requesting application.
The PPS Server AE initiates the following functions.
Start PPS: Initiates a DICOM association in order to create a DICOM Modality Performed Procedure
Step SOP instance in the remote AE. If the remote AE accepts a presentation context applicable to
Modality performed Procedure Step, the PPS Server AE will issue a request to create the SOP
instance in the remote AE via the N-CREATE service.
Complete PPS: Initiates a DICOM association in order to update a DICOM Modality Performed Step
instance that is already created with the remote AE. If the remote AE accepts a presentation
context applicable to Modality performed Procedure Step, the PPS Server AE will issue a request to
update the SOP instance in the remote AE via the N-SET service. The PPS Status is set to
‘COMPLETED’.
Discontinue PPS: Initiates a DICOM association in order to update a DICOM Modality Performed
Step instance that is already created with the remote AE. If the remote AE accepts a presentation
context applicable to Modality performed Procedure Step, the PPS Server AE will issue a request to
update the SOP instance in the remote AE via the N-SET service. The PPS Status is set to
‘DISCONTINUED’.

Sequencing of Real-World Activities
2.3.1.2.7.1.1 PPS from Acquisition System with MWL data
The system has a Modality Work-list Server AE installed. Work-List information is obtained from HIS/RIS
system through the use of Basic Work-list Management Service. Use of the information retrieved in
the creation of Image SOP instance is described in the Modality Work-list Conformance statement. Use
of the information retrieved in MPPS SOP instances is described later in this document.
The system initiates a ‘Start PPS’ before starting a scan, i.e. when the image acquisition is started.
The system retrieves necessary information related to the Scheduled Procedure Step from Modality
Work-list Server. PPS Server AE initiates a MPPS (Modality Performed Procedure Step) N-CREATE
request to the remote AE (MPPS SCP), in-order to create a MPPS SOP instance at the remote AE.
The MPPS SCP returns response indicating the success/failure of the request execution. The PPS
state information is updated in the system based on the response data, and is presented to the
user. The DICOM association is closed.
System includes the necessary information related to Scheduled Procedure Steps and the
Performed procedure Step in the image instances created.
At the end of image acquisition, system initiates a ‘Complete PPS’ or ‘Discontinue PPS’ based on
the choice selected by the user using the user interface provided. The user is also given a choice
‘Defer PPS’ which is described below. PPS Server AE initiates a MPPS N-SET request to the remote

The remote AE returns response indicating the success/failure of the request execution. The PPS
state information is updated in the system based on the response data, and is presented to the
user.
At the end of image acquisition, if the user has chosen ‘Defer PPS’, the user is provided with an
interface to ‘Complete PPS’ or ‘Discontinue PPS’ at any later time. The user might wish to alter the
image set generated through acquisition, before invoking these operations. Note that the user
explicitly uses the user interface provided to invoke this operation, as in the case of PPS generated
for post-processing, which is described in the following section. PPS messages N-CREATE ( if
applicable) and N-SET will be sent over the same DICOM association
The remote AE returns response indicating the success/failure of the request execution. The PPS
state information is updated in the system based on the response data, and is presented to the
user.
2.3.1.2.7.1.1.2 PPS from acquisition system without MWL data
The system either does not have a Modality Work-list Server AE installed or a Modality Work-list Server
AE installed but no Work-List information is obtained from HIS/RIS system for the current procedure
that is being performed. The information required for performing the procedure is supplied through
the user interface of the system. The use of this information in MPPS SOP instances is described later
in this document.
The system initiates a ‘Start PPS’ before starting a scan, i.e. when the image acquisition is started.
PPS Server AE initiates a MPPS (Modality Performed Procedure Step) N-CREATE request to the
remote AE (MPPS SCP), in-order to create a MPPS SOP instance at the remote AE.
The MPPS SCP returns response indicating the success/failure of the request execution. The PPS
state information is updated in the system based on the response data, and is presented to the

2.3.1.2.7.1.1.3 PPS from post-processing system
The user initiates post-processing on the images generated through acquisition.
The system creates a Modality performed Procedure Step instance locally in the system. If the
source image instance has the Scheduled Procedure Step information, it is copied into the image
instances created. Also the system includes the necessary information related to the Modality
Performed Procedure Step into the image instance.
At the end of (one or more) post-processing, the user initiates ‘Complete PPS’ or ‘Discontinue PPS’
through the user interface provided. PPS Server AE initiates a MPPS (Modality Performed Procedure
Step) N-CREATE request to the remote AE (MPPS SCP), in-order to create a MPPS SOP instance at
the remote AE (which is actually a replica of the locally created MPPS SOP instance).
The remote AE returns response indicating the success/failure of the request execution. If the
response indicates success, PPS Server AE initiates a MPPS N-SET request to the remote AE, inorder to update the MPPS SOP instance that is already created, with the additional information.
The remote AE returns response indicating the success/failure of the request execution. The PPS

2.3.1.2.8 Real-World Activity: Print
2.3.1.2.8.1 Associated Real-World Activity
The Film Composer allows the user to select printers and it also allows the user to drag and drop the
images (from the viewer application) into the film. It also allows the user to manipulate some print
parameters like film format and number of copies to print. When the user presses the "Print" Button,
the Film composer communicates this request to Print SCU, which then tries to establish the
association with the requested printer and transmits the images for printing.

2.3.1.2.8.1.1 Sequencing of Real-World Activities
The DICOM printer is installed through a camera installation process. The DICOM printer is
selected from the Film Composer Interface for Manual Filming. Autofilming is enabled using the
camera setup via the camera installation process.
Images may be acquired for printing in the following manner:
–
Images to be printed may be manually dropped from Viewing
applications into the manual film composer slots.
–
Images to be printed may be automatically dropped from Viewing
applications into the manual film composer slots.
–
Images to be printed may be manually dropped from Viewing
applications into the auto film composer slots.
–
Image series to be printed may be automatically dropped from the
Print Series application into the manual film composer slots.
–
Images to be printed may be automatically dropped from the
Scanning Application into the auto film composer slots.
Based upon the filming mode (and the attributes) used to acquire images into the
film composer, films will be automatically printed when the film session is full, or the user must
press the Print Button to print the images.
The Print SCU will start the Print Session. The Print Session involves establishing association with
the printer followed by the next sequence of activities:
-
The Print SCU gets the Print SCP status using N-GET service. If the Printer returns FAILURE
status the print session will be terminated and the requester will be notified of the printer
status.
-
The film session is created using N-CREATE service. In case of error, the print session will be
terminated. The attribute values for the Film session will be specified with the film session
request.
-
The film box is created using N-CREATE service. The print session will be terminated if the
printer fails to create the film box. The film box attribute values will be sent in the film box
create request
-
The image attributes for the images to be printed in this session will be set using the N-SET
service. If the printer fails to accommodate the images in the image set, the print session will
be terminated. The film will be printed using the N-ACTION service. Only film box printing is
supported. In case of error, the print session will be terminated.
-
The Film Box instance will be deleted using the N-DELETE service.
-
The SCU does not wait for N-EVENT-REPORT from the Printer after deleting the film box
instance. The N-EVENT-REPORT received when the association was still active is handled,
but the data received will be ignored.

Finally the association will be terminated and if all the above operations are successful the
requester will be notified of the successful print session. This status just indicates that the
images to be printed have been successfully sent to the printer.

REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
When the DICOM Server AE accepts an association for image storage, it will receive any images
transmitted on that association and store the images on disk.
It will also respond to queries from Remote AEs by sending matching entries. Any Remote AE can
request and receive a list of images on the local database. The Remote AE must be configured in the
local database manager’s list of Remote AE for it to be able to retrieve images from DICOM Server AE.
Any remote AE can open an association to the DICOM Server AE for the purpose of verification.
2.3.1.3.1 Real-World Activity: Receive Images
This AE is indefinitely listening for associations. No operator action is required to receive an image.
2.3.1.3.1.1 Associated Real-World Activity
The Real-World Activity associated with the Receive Images operation is the storage of the image on
the disk drive of the GEHC CT.

accept the first one.
2.3.1.3.1.2.1 SOP Specific Conformance to C_STORE SCP
The DICOM Server AE conforms to the SOP’s of the Storage Service Class at level 1 (base).
Each C-STORE SCP operation supports an “Association Timer” and “Operation Inactivity Timer” with
time out values of 30 seconds, 15 seconds respectively.
Association Timer – duration for SCP to respond to an association request.
Inactivity Timer – duration between two commands after the association.

In the event of a successful C-STORE operation, the image has successfully been written to
disk. The image will then be accessed in the same manner as any other image by the
applications on the GEHC CT system.
Images may be deleted when instructed to do so by the user. Thus the duration of the storage
of the image is determined by the users of the GEHC CT system.
Image Installation
If the image installation is unsuccessful, a message will appear in the Message Log informing
the user of the failure and the image will be removed.
If the image installation process finds that an element is not encoded according to the DICOM
standard, it will fail to install the image and the file will be removed.
Image Installation of non-GE Created MR or CT Images
Images received from non-GE products are installed as the appropriate image object. Their
private data elements will be maintained if the negotiated transfer syntax is Explicit Little or
Big Endian. Also if any critical fields (mandatory) are missing, then the image will not be
installed.
This AE is indefinitely listening for associations. No operator action is required to respond to a
verification message.

SOP Specific DICOM Conformance Statement for the Storage Commitment Push Model SOP Class
(N-EVENT-REPORT)
The DICOM SERVER AE monitors an “Operation Inactivity” timer. The connection with the SCU will be
terminated if it is inactive for the configured time-out interval. Default time-out is 15 seconds and is
configurable.
Once the N_EVENT_REPORT response is received from the SCP, the following actions will be taken
depending on the status of response.
2.3.1.3.5.2.1.1
Commitment response with SUCCESS status
The “Archived” flag information in the browser for all the successfully archived exam/series will be
updated. The archive status column in the browser will be changed to display “Archived” icon to
indicate that the exam/series has been archived successfully. The job queue entry will be removed.
N_EVENT_REPORT response will be sent on the same association as N_EVENT_REPORT request. No
data set will be sent along with the response.
Following are the status codes the Application may send back to the SCP Equipment after receiving
the N-EVENT-REPORT:

Commitment response with FAILURE status
In the event of complete/partial failure the user will be notified about the status and the job entry will
be paused. There is no attempt made to automatically retry the failed SOP instances. However the
user can manually retry the failed jobs. Such requests will be treated as new requests. This will go
through the complete sequence of operations once again.
The failure reason is ignored. Failed SOP instances will have their “Archived” flag information
unaltered. Failed SOP instances are logged.
Note: The archived status flag in the browser is a shared flag with local archive. When the status is
“Archived”, it means that the images are archived but doesn’t specify whether on local archive
device or remote archive device. It is left to the user’s discretion whether the local SOP instances are
to be deleted.
N_EVENT_REPORT response will be sent on the same association as N_EVENT_REPORT request. No

REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
MEDIA STORAGE CONFORMANCE STATEMENT
Introduction
This conformance statement specifies the GEHC CT conformance to the DICOM Media Interchange. It
details the DICOM Media Storage Application Profiles and roles that are supported by this product.
GEHC CT system provides capabilities to DICOM interchange on CD-R (Compact Disc - Recordable),
CD-RW (Compact Disc - ReWritable), DVD-R (Digital Video Disc - Recordable), DVD-RW (Digital Video
Disc - ReWritable) and USB (Universal Serial Bus) memory.
GEHC CT system works with most of the IOD’s like Computed Tomography (CT), Magnetic Resonance
(MR), Computed Radiography (CR), Positron Emission Tomography (PET).
3.2
Implementation Model
The DICOM Interchange Archive Server Application Entity (AE) handles all DICOM media storage
functionality on the GEHC CT system.
The DICOM Interchange Archive Server AE is commanded to perform DICOM services through the
buttons and menu selections on the user interface. It also uses the appropriate recorders to provide
the service Interchange Media profiles.
3.2.1 Application Data Flow Diagram
The Basic and Specific Application models for the CD-R/CD-RW/DVD-R/DVD-RW/USB devices are
shown in the following Illustrations.
The DICOM Interchange Archive Server Application Entity (AE) handles the DICOM CREATE CD
(/DVD/USB) / RESTORE CD (USB) / QUERY CD (USB) functionality for the CD/DVD/USB media. The
DICOM Interchange Archive Server Application Entity (AE) is commanded by the user to perform
DICOM services operating on the DICOM media through the use of buttons and menu selections on
the graphical user interface of the platform.
The user requests the creation of a DICOM File Set and the writing of this DICOM File Set on blank
Interchange Media by selecting images in the local Browser and selecting the Interchange Media as
being the selected device. Then, the iso9660 image of the CD/DVD/USB to write will be generated.
Once the generation has been done, it writes the complete set of data on the selected Interchange
Media.
The Media Interchange Application Model for the GEHC CT system is shown in Illustration 3-1:

CREATE
The DICOM Interchange Archive Server AE has a local storage that may contain various SOP
instances. These may have been obtained by original creation, network (DICOM or proprietary) or by
removable media using other application entities. These instances are external to this conformance
claim and the origin of SOP instances is outside the scope of this claim.
The DICOM Interchange Archive Server AE can initialize Media by acting as an FSC to create a new
DICOM File-set on a blank interchange media. It initializes the DICOM File-set and writes the specified
SOP instances onto the Interchange Media at once. The SOP instances written will be limited to
instances that match the criteria of one of the Application Profiles that is supported.
Updating the media is not supported.
3.2.2 Functional Definitions of AE's
The CD-R/ CD-RW/DVD-R/DVD-RW/USB DICOM Interchange Archive Server Application Entity
support the following functions:
·
Generate and write a DICOM File Set (FSC) in a one shot activity. (CREATE).
·
Read a DICOM File Set (FSR) on an Interchange Media (QUERY).
·
It can copy SOP instances from the media onto local storage. (RESTORE).
3.2.3 Sequencing of Real World Activities
The display function (QUERY) can only be performed on a piece of media that already had a DICOM
File-set created. With no SOP instances having been added, the directory will be displayed empty.

Real World Activity:
Record Media - CREATE (CD/DVD/USB)
The DICOM Media Interchange Application acts as an FSC using the interchange option when
requested to copy SOP Instances from the local database to a CD-R / CD-RW / DVD-R / DVD-RW /
USB.
The user selects the entries in the local database that he/she wants the DICOM Media Interchange
Application to copy onto Interchange Media.
The graphic interface allows the user to select the entries (studies, series or images) in the local
database to be copied onto to the selected Interchange Media.
The DICOM Media Interchange Application creates one File Set per generated Interchange Media.
The graphic interface allows the user to select the entries (studies, series or images) in the local
database to be copied onto to the selected Interchange Media.
A user cannot create CD/DVD/USB while restore CD/USB is in process.
A DICOM Media Viewer is provided along with the selected object instances on the interchange
media. This viewer can be loaded on a standard PC running Windows XP, Windows Vista or
Windows 7.
Before writing on the Interchange Media, the DICOM Media Interchange Application checks for the
following condition:
The inserted media is blank and write-able. If the condition is not met, an error is displayed and
the user needs to replace it with a blank media.
Note:
Since JPEG compression is not enabled, the transfer syntax for SOP Instances will always be Explicit
VR Little Endian (ELE) Uncompressed Transfer Syntax, UID 1.2.840.10008.1.2.1. For any other IODs
with Transfer syntax other than ELE, the corresponding SOP instance data are converted to ELE and
then copied to CD/DVD/USB. During the conversion to ELE, the private tags are stored with VR as UN
if the syntax is implicit to facilitate fidelity.

Modality Worklist Information Model Definition
6.1.1 Introduction
This section specifies the use of the DICOM Modality Worklist Information Model used to organize
data and against which a Modality Worklist Query will be performed.
6.1.2 Modality Worklist Information Model Description
In order to serve as a Service Class Provider (SCP) of the Modality Worklist Service Class, a DICOM
Application Entity (AE) possesses information about the attributes of a number of managed worklist
items. These items are organized into Modality Worklist Information Modules. In this Service Class,
the Information Model plays a role similar to an Information Object Definition of most other DICOM
Service Classes.
6.1.3 Modality Worklist Information Model Entity-Relationship Model
The Entity-Relationship diagram for the Modality Worklist Information Model schema is shown in
Illustration 6.1.3-1. It represents the information that composes a Worklist Item. In this figure, the
following diagrammatic convention is established to represent the information organization:
Each entity is represented by a rectangular box
Each relationship is represented by a diamond shaped box.
The fact that a relationship exists between two entities is depicted by lines connecting the
corresponding entity boxes to the relationship boxes.

6.1.3.1.1 Scheduled Procedure Step
A Scheduled Procedure Step is an arbitrarily defined scheduled unit of service that is specified by the
Procedure Plan for a Requested Procedure. It specifies one or more Action Items (events) involving
equipment (i.e. imaging modality equipment), human resources, location and time (i.e. start time, stop
time, duration).

A Requested Procedure is an instance of a Procedure of a given Procedure Type. An instance of a
Requested Procedure includes all of the items of information that are specified by an instance of a
Procedure Plan that is selected for the Requested Procedure by the imaging service provider.
6.1.3.1.3 Imaging Service Request Entity Description
An Imaging Service Request is a set of one or more Requested Procedures selected from a list of
Procedure Types. An Imaging Service Request is submitted by one authorized imaging service
requester to one authorized imaging service provider in the context of one Service Episode.
6.1.3.1.4 Visit Entity Description
A Visit is the context in which the treatment or management of an arbitrary subset of a Patient’s
medical conditions occurs. A Visit is limited to the description of a Patient’s activities at a single
facility.

6.1.5 Modality Worklist Information Model Module
Within an entity of the DICOM Modality Worklist Information Model, attributes are grouped together
into related set of attributes called modules. A module facilitates the understanding of the semantics
concerning the attributes and how the attributes relate to one another. A module grouping does not
infer any encoding of information into datasets.
Table 6.1.5-1 identifies the defined modules within the entities that comprise the DICOM Modality
Worklist Information Model. Modules are identified by Module Name.
See DICOM PS 3.3 and PS 3.4 for a complete definition of the entities, modules, and attributes.

C-FIND Request Message
This section provides a detailed description of the C-FIND request message data that is
provided to the remote AE during a worklist query operation. The dump in Table 6.4-1 below
lists, in exact message order, the fields transferred as part of the C-FIND request message for a
typical query.
In this particular dump, no values are specified for the Scheduled Procedure Step Start and
End Dates (the attributes are sent with zero length). In DICOM this is interpreted as meaning all
dates (i.e. universal matching). The Modality is also not specified in this particular dump,
meaning all modalities. Note that the user, through the use of the GEHC CT user interface, can
submit a worklist query that will cause non-zero values to be sent for these attributes.

REVOLUTION ACTS DICOM CONFORMANCE STATEMENT
PERFORMED PROCEDURE STEP CONFORMANCE STATEMENT
Introduction
This section of the DICOM Conformance Statement specifies the compliance to DICOM
conformance requirements for the Modality Performed Procedure Step feature on this GEHC
product. Note that the format of this section strictly follows the format defined in DICOM
Standard PS 3.2 (Conformance). Please refer to that part of the standard while reading this
section. The PPS option for GEHC CT allows a Modality Performed Procedure Step to be
communicated to the Hospital/Radiology information system. The PPS feature is providing the
DICOM Modality Performed Procedure Step service as a service class user (SCU).
This feature works in conjunction with DICOM Modality Worklist feature, if installed. However
the conformance of this feature is independent of Modality Worklist feature. For information
on conformance of Modality Worklist feature to DICOM standard please refer to the
appropriate section or document.
7.2
N-CREATE & N-SET Request Message
PPS Feature for GEHC CT supports all named attributes listed in Table F.7.2.1 in PS3.4 of DICOM
standard. That is, attributes that are not explicitly referenced by name in the table are not
supported. (Example is last row in the table reads “All other attributes from Radiation Dose
Module and Billing and Material Code Module”. The attributes referenced here are not
supported).
For the MPPS associated with an acquisition, the following attributes are copied from the
Modality Worklist SCU into the MPPS request Message, if procedure performed corresponds to
the SPS information retrieved through the Modality Worklist.
GEHC CT supports the selection of single or multiple SPS for a scan. The following are
applicable.
Single SPS selection results in single PPS message
Multiple SPS selection results in single PPS message
Multiple SPS selection is allowed only if they all correspond to same patient id
A maximum of 15 SPS’s can be selected
Referenced Study Sequence - a maximum of ten Item’s is supported. This attribute will be
present only if SPS information is available from Modality Worklist SCU.
At the end of acquisition the user might choose to ‘Defer PPS’ and later choose to
‘Complete PPS’ or ‘Discontinue PPS’ from the user interface provided in the system. In this
case, the date and time when user chooses to ‘Complete PPS’ or ‘Discontinue PPS’ is taken
as the Performed Procedure Step End Date and Performed Procedure Step End Time
respectively (Not the actual end date and end time of acquisition)
Mapping of SPS data to MPPS SOP instance is explained in section 7.3

Configuration
The product is configured by default to not generate the CT X-Ray Radiation Dose SR Record.
Creation of the CT Dose Record can be enabled via reconfig.
The product implements the CT Radiation Dose Report template (TID 10011) per DICOM Supplement
127.
The DICOM standard says that the SOP class shall be the “X-Ray Radiation Dose SR” SOP Class
(1.2.840.10008.5.1.4.1.1.88.67).
However, since many products may not support this SOP class, the product supports the option via
reconfig to create the CT Radiation Dose Report as an “Enhanced SR” SOP Class
(1.2.840.10008.5.1.4.1.1.88.22).

GE HEALTHCARE

SR setting can be configured in “Dose Report” in reconfig menu as below.
“Full” will produce the X-Ray Radiation Dose SR SOP class
“On” will produce the Enhanced SR SOP class.
“Off” will not produce any SOP class.

10 Security Conformance Statement
10.1 De-identification
The GEHC CT system satisfies the following requirements for de-identification
De-identification occurs, for example, when an anonymous patient operation is performed. This deidentification only covers DICOM attributes that contain protected patient information. The encrypted
data capability is not supported, so once an image has been de-identified no facility is provided to
recover the lost information.
The de-identification specified in this section only applies to GE generated images. All third party
images have only the standard DICOM elements de-identified, all private tags (non-GE private tags)
within these images are dropped.
De-identification supports the following object types:
· CT Image Objects
De-identification does not support the following object types:
· Secondary capture images
· Structured reports
· Grayscale presentation state objects
This de-identification specification applies when the GEHC CT system is configured for full deidentification. If the system is configured for partial de-identification, some attributes will remain
unchanged.
Table 10.1-1 provides the list of attributes and the expected action when de-identifying images.

ASSOCIATION LEVEL SECURITY
The GEHC CT system provides association level security for Query Retrieve operations.
The system will only allow remote DICOM servers to pull images if the remote DICOM server is defined
on the GEHC CT system. The remote DICOM server’s IP address, AE title, and Port number must be
configured on the GEHC CT system for the networking pull to begin.
Note that this association level security only applies to the retrieve request; query operations will be
accepted from any connected DICOM client.

Value always sent.
Image Slice Location
(0020,1041)

Value always sent. Note: Slice Location
reflects the gantry ISO center table location
value for the image in mm. If the gantry is
tilted, this value will differ from the image
position (0020, 0032) Z value which reflects
the upper left-hand voxel (center of the first
voxel transmitted) of the grid, in mm in the
registered Frame of Reference. The system
can be configured to save the upper lefthand corner Z coordinate value into (0020,
1041) Slice Location instead of the gantry ISO
center table location.
Image Position

Always sent. System configuration allows
images to be flipped and rotated. Default
behavior is to not allow flip and rotate. Note
that the Image Position reflects the x, y and z

voxel transmitted instead of the center of the
first voxel transmitted.

Later point of time, if we get the patient ID then the above dummy patient ID should be updated
with the actual patient ID.
Scenario:
=========
For example if we are adding 8 images, and 4 images are of Series S1 and 4 images are of series
S2 belonging to the same Study as S1. Series S1 images are not having any value for patient ID but
series S2 images are having the value of patient ID. Now while DICOMDIR creation, initially we
would put dummy patient ID value when iterating through series S1 but when we reach to the
second series image then previously filled dummy patient ID should be filled with the actual patient
ID found in series S2 images.
Another example: if several series belong to a same Study without Patient ID in any of the images,
a single Patient ID (i.e. a single Directory Record) is assigned to this Study, and all Series are
attached to the Study they belong to. Do not duplicate Study UIDs (i.e. do not generate two
Directory Records with the same Study UID).
