Conformance Statements

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:

1.3 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.

1.5 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.

1.7 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.

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

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

S

DICOM C

ONFORMANCE

S

TATEMENT

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

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 Series-

Level C-FIND-RQ request to get the series for a study in the list. Similarly the Image-Level C-FIND-

RQ 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-ECHO-

RSP 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

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-CANCEL-

MOVE-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.

2.3.1.2.1.2.1 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


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.


When the Real-World activity “Manual Query” is initiated all presentation contexts shown in the following table are proposed during association establishment, but only the Query/Retrieve-FIND related contexts are applicable to this activity.

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

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-FIND-

CANCEL 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 Real World Activity: Manual Retrieve


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. Once a list of Study/Series/Image is retrieved, the operator can invoke the “Retrieve” operation by clicking on the “Local DB” button at the bottom of the local database browser.


When the Real-World activity “Manual Retrieve” is initiated all presentation contexts shown in the following table are proposed during association establishment, but only the Query/Retrieve-MOVE related contexts are applicable to this activity.

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 Associated Real World

Activity: “Auto Archive Exam/Series”

The Auto archive API’s are used to archive the exams/series onto local archive media or the remote archive node (which shall be a Storage Commitment SCP) without manual interface. If the default device selected for Auto Archive is a remote Storage Commitment SCP then all the images currently in the specified exam/series will be sent to the selected Storage commitment SCP using C-STORE operations. On successful transfer of all the images the Storage Commitment request will be sent.

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 applicable for these requests.

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’.

2.3.1.2.7.1 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

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 following table shows the proposed presentation contexts for the PPS Server AE after any of the real-world activity listed in section 2.3.1.6.1 Sequencing of Real-World Activities, is initiated.

2.3.1.2.8 Real-World Activity: Print


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.

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.

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.

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.

(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.

2.3.1.3.5.2.1.2 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 data set will be sent along with the response.

3 MEDIA STORAGE CONFORMANCE STATEMENT


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.

Application Entity

3.3.1.2.1 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:



Note:

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.

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.

3.3.1.2.2 Real World Activity: Display Directory – QUERY (CD/USB)

The DICOM Media Interchange AE acts as an FSR using the interchange option when requested to browse the Interchange Media.

When the DICOM Media Interchange AE is requested to provide a directory listing, it reads the Fileset and displays the DICOMDIR directory entries, according to the STUDY Root paradigm.

If the media is not blank, then Interchange Media gets mounted. To remove the media, the user has to select the eject button on user interface for the appropriate drive.

A user cannot display the directory when create CD/DVD/USB or restore CD/USB are in progress.

The CD/USB DICOM Media Interchange AE acts as an FSR using the interchange option when requested to copy SOP instances from the CD/USB to the local database.

The user selects the SOP instances that he wants the DICOM Media Interchange AE to copy on the local database by selecting appropriate Study/Series/Image instances and clicking on the suitable restore buttons. Once selected, the SOP instances are copied from the media to the local database.

If the media is not blank, then the Interchange Media gets mounted. To remove the media, the user has to select the eject button on the User Interface for the appropriate drive.

A user cannot restore CD/USB while create CD/DVD/USB is in process.

A user can only restore selected composite objects at a time from a media; any other attempt of selections to restore CD/USB on media in same drive will wait until the first one is completed.

6 Modality Worklist Information Model Definition

6.1 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.

6.1.3.1.5 Patient Entity Description

A Patient is a person receiving, or registered to receive healthcare services.

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.

6.3 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.

7 PERFORMED PROCEDURE STEP CONFORMANCE STATEMENT


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

Note: CT X-Ray Radiation Dose SR Record adheres to the DICOM 2011 edition.


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).

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.

10.2 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. 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.

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 coordinate of the upper left corner of the first 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).
