SECTION 1 - INTRODUCTION
1-1
OVERVIEW
This document is the Introduction to the Integrated DICOM/Network v3.0 (ID/Net
v3.0)Conformance Statement. It is applicable to all GE Medical Systems (GE) products
which support the ID/Net v3.0 network. More specifically, this document is an introduction
to the Conformance Statements related to GE ID/Net products.
Section 1 provides general information about the GE strategy for Open Connectivity. It
includes a brief description of the relationships of GE ID/Net v3.0 and the DICOM V3.0
standards and also includes important remarks which users of ID/Net should address
carefully when connecting imaging systems.
Section 2 is an overview of network architecture concepts, including the ISO seven layer
model and the DICOM Applications Layer model.
Section 3 describes the basic technical concepts and terminology which are used in the
DICOM standard and the ID/Net environment.
Section 4 provides some basic reference material (references, definitions, acronyms) for
DICOM and ID/Net which is common to all GE DICOM Conformance Statements.
1-2
INTENDED AUDIENCE FOR THIS
DOCUMENT
This document is intended for a broad audience in areas of medical imaging, software
design, network planning, and/or systems integration. The reader must have a basic
understanding of networking. The purpose of this document is to familiarize the reader with
some of the ID/Net and DICOM v3.0 terminology and concepts.
If, however, the reader intends to work at the software implementation and/or systems
integration levels, this Introduction will be helpful, but insufficient. In this case the reader
must also read the DICOM v3.0 standard and the specific product Conformance Statements.
1-3
CONNECTIVITY FOR INCREASED EFFICIENCY
Connectivity is desirable for a number of reasons since it may provide clinical benefits and
may increase the following departmental efficiencies:
D
D
D
D
Rapid availability of images to diagnosticians and clinicians.
Ease of exchange of images between locations (remotely or locally).
Ease of image access for filming, reading, archiving (off-loading the tasks from
scanners), or advanced analysis (3D, DentaScan).
Integration of image acquisition and diagnostic information into the hospital inĆ
formation system, a necessary step toward patient record consolidation.
The benefits of shared digital information may include simultaneous access of information
by multiple users, post processing of image data, reduction in film loss, reduction in film
storage space, etc., which may result in increased productivity, efficiency,
cost-effectiveness, and improved patient care. To pursue these potential benefits the
concept of “Networked systems” must be incorporated. Fully networked systems are
capable of interoperating to communicate image and related information. Simply being
connected to a network does not mean that two devices can interoperate, that is, send,
receive, display, analyze, or archive data, etc. ID/Net provides the interoperability
foundation for networked devices, thus allowing customers to begin to choose equipment
optimized for a particular application.

THE NEED FOR A STANDARD
True connectivity requires the definition and implementation of a common network
communications standard among manufacturers, one that addresses a wide variety of
imaging components – image acquisition equipment, display workstations, archiving
systems, hard copy devices and information management systems, for example.
DICOM has emerged as the medical information networking standard, currently defining
CT, MR, Nuclear Medicine, Ultrasound and Computed Radiography images, as well as
Laser Camera and HIS/RIS interfaces. Also, the definition of X–Ray Angiography and
Media Interchange is well underway. The development of DICOM has been the result of
joint effort between NEMA (Medical Imaging Vendors) and the ACR (American College of
Radiology). Other medical specialties have also contributed to this effort, in particular the
ACC (American College of Cardiology).
DICOM is also a global standard. In particular, CEN in Europe is actively involved in the
definition of DICOM standards and has decided to use DICOM as the basis for a European
Standard. An active liaison also exists with the JIRA and IS&C committees in Japan. GE has
been a major contributor to the development of this standard, and implementation of these
DICOM concepts is realized in the GE ID/Net v3.0.
1-5
ID/NET - AN OPEN, INTEGRATED INTERFACE
The GE Integrated DICOM/Network v3.0 allows users to connect among GE DICOM
imaging systems, as well as to other manufacturers’ DICOM–based products. GE ID/Net
v3.0 is a DICOM–based implementation which provides a common, open networking
approach for medical imaging equipment. ID/Net is the interoperability foundation for a
wide range of GE products and for interfacing with third party devices.
ID/Net provides the flexibility to configure, in many cases, network solutions that meet GE
customers’ diverse communication requirements. ID/Net also inherently provides for the
option of purchasing standard network devices, such as cabling, transceivers, modems,
routers, bridges, etc., to meet most network needs.
Because ID/Net is based upon networking standards, the size and configuration of health
care site networks are flexible. The networking standards allow different technologies to be
employed (e.g., wide area networks, local area networks, etc.).
With GE and ID/Net, you have the ability to begin accessing the benefits of connectivity
today – and a solid link to the future.
1-5-1
ID/Net - An Integrated Network
ID/Net is integrated. DICOM standards are an integral part of product design, so investment
in costly and complex gateways often needed to network between dissimilar proprietary
networks is not likely (some older equipment may be an exception.)
1-5-2
ID/Net - An Open Network
ID/Net is open. It enables connectivity to other manufacturers’ DICOM–compatible
equipment. GE ID/Net interfaces are documented in DICOM Conformance Statements. If
your current systems have not been built to DICOM standards, third party connections may
be used to convert proprietary image format into DICOM standards.

ID/Net - Support by GE Products and ID/Net DICOM Conformance Statements
A number of GE systems are already demonstrating the effectiveness of ID/Net v2.0 and/or
ID/Net v3.0 connectivity. Among them are our CT 9800, HiLight and HiSpeed Advantage
systems, as well as MR Signa 5.X systems, Advantage Independent Consoles, and
Advantage Windows workstations. As the DICOM standard evolves, additional modalities
and connections are expected to be implemented.
For more specific information regarding current product capabilities and availability, please
contact your GE Sales representative.
For the purposes of backward compatibility, the CT Advantage, MR Signa 5.x Advantage,
and CT9800 ID/Link II continue to support ID/Net v2.0. This continuum in network
connectivity is presented in section 1–5–4.
Any GE equipment which supports ID/Net will have a “DICOM Conformance Statement”
available to the public. The Conformance Statement is an implementation profile which
lists the DICOM functions (e.g., send a CT image, send an MR image, query for images,
etc.) which have been implemented by a particular piece of equipment.
The DICOM standard, and thus ID/Net, is structured such that each device can implement
the appropriate functions of the standard for its intended application. In order for two
devices to interoperate, both devices must have a complementary set of functions
implemented. As part of the standard, two devices negotiate before they begin to
communicate to verify that the common function(s) does exist. However, before attempting
to interoperate, the existence of a set of common functions should be determined by
reviewing the Conformance Statement of each device. For example, a product could
implement the “image send” function, but not the “image receive” function.
The exact technical specification of how ID/Net v3.0 implementations conform to DICOM
v3.0 is given in each GE product ID/Net DICOM Conformance Statement. It is the intent of
this document (“Introduction to the ID/Net v3.0 Conformance Statement”) to provide
introductory information which is common and applicable to all ID/Net DICOM
Conformance Statements.
The Conformance Statements may be ordered by specifying the Direction number, as
defined in the “Overall ID/Net Documentation Structure”, section 1–7.
1-5-4
ID/Net v3.0 Compatibility with ID/Net v2.0
ID/Net v2.0 products were released before the DICOM Standard was completed. ID/Net
v2.0 is a network protocol based on the DICOM Part 8 network communications
specification, but with GE specific Information Object Definitions (IOD’s). The GE IOD’s
are publicly available as the “ID/Net v2.0 Implementation Profiles”, Direction
46–269546G2, and are based on the April 1993 draft version of DICOM v3.0.
ID/Net v3.0 is fully compliant with the final version of DICOM v3.0, but also backward
compatible with ID/Net v2.0 as shown in Illustration 1–1.
1-6
IMPORTANT REMARKS
The use of these Conformance Statements, in conjunction with the DICOM v3.0 Standards,
is intended to facilitate communication with GE imaging equipment. However, by itself, it
is not sufficient to ensure 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 interconĆ
nected devices goes beyond the scope of standards (DICOM v3.0), and of this
introduction and associated Conformance Statements when interoperability
with non-GE equipment is desired. The responsibility to analyze the applicaĆ
tions requirements and to design a solution that integrates GE imaging equipĆ
ment with nonĆGE systems is the user's responsibility and should not be
underestimated. The user is strongly advised to ensure that such an integration
analysis is correctly performed.
D
Validation - Testing the complete range of possible interactions between any GE
device and nonĆGE devices, before the connection is declared operational,
should not be overlooked. Therefore, the user should ensure that any nonĆGE
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 nonĆGE 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 developĆ
ment of the DICOM v3.0 Standard. DICOM v3.0 will incorporate new features
and technologies and GE may follow the evolution of the Standard. ID/Net v3.0
is based on DICOM v3.0 as specified in each ID/Net DICOM Conformance
Statement. Evolution of the Standard may require changes to devices which have
implemented DICOM v3.0. In addition, GE reserves the right to discontinue or
make changes to the support of communications features (on its products) reĆ
flected on by these ID/Net DICOM Conformance Statements. The user should
ensure that any nonĆGE provider, which connects with GE devices, also plans for
the future evolution of the DICOM Standard. Failure 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.
D
Interaction - It is the sole responsibility of the nonĆGE provider to ensure that
communication with the interfaced equipment does not cause degradation of GE
imaging equipment performance and/or function.

SECTION 2 - 2-1
OVERVIEW
The second part of this document describes some of the Network Architecture concepts and
models which are used in ID/Net v3.0 and DICOM v3.0. ID/Net v3.0 is fully based upon
DICOM v3.0.
2-2
A successful network architecture must be layered to facilitate integration of evolving
technologies. The Open Systems Interconnection (OSI) Reference Model defined by the
International Standards Organization is the accepted seven layer model for the design of
modular network architectures.
The purpose of this Section is to provide a brief explanation of the OSI networking
architecture. Section 2–2–1 provides some analogies to introduce these concepts. Section
2–2–2 illustrates how DICOM is based on the OSI reference model.
2-2-1
Network Architecture and the Post Office Analogy
The fundamental choices made by the DICOM v3.0 Standard can be understood by
comparing a digital medical image network to a postal system. A postal system is complex,
employing computers to track and route mail, and trucks, trains, and airplanes to move mail.
But for the end user, the complexity of the system is transparent.
When it comes to the content of the envelope, the two people who want to communicate
need a common language for writing the letter. If they do not speak the same language but
both know a third language, the third language would be the common language, the
language of communication. For example, if a French person and a Japanese person both
spoke English and they wanted to write to each other, they would go through this process
(refer to Illustration 2–1 as you read the steps below it):
ILLUSTRATION 2-1
1.. The letter is composed in the writer's native language, for example, French.
2.. The letter is translated into English.
3.. The letter is inserted into an envelope, and the envelope is addressed to meet the
postal system's requirements.
4.. The letter is put into a mail box, picked up by the writer's post office and sent
across town or around the world.
5.. The letter is received by the reader's post office.
6.. The address on the envelope is read, and the letter is delivered to that address.
7.. The letter is opened and read in English.
8.. The English is translated into the reader's native language, for example, JapaĆ
nese.

After packaging and addressing a letter and putting it into a mailbox, the postal system takes
over and performs Steps 4 and 5. The letter could travel by truck, train or plane. The method
of transportation does not matter as long as the letter is reliably delivered to its destination.
Refer to Illustration 2–2 as you read the following:
H The devices on a digital medical network are similar to the businesses on a postal
H
system. Just as each business is different, the devices can be different. They inĆ
clude workstations, image acquisition devices, information systems, image storĆ
age and distribution control devices, gateways, hard copy printers and other
peripherals.
The imaging and text data being transferred across a digital medical network vaĆ
ries, just as the contents of letters being carried by the postal system varies. The
postal system does not care about the contents of the letters it delivers, nor does
it alter the contents. In a similar manner, digital medical networks should transfer
image and text data without altering the information.

H The postal system delivers both small envelopes and large packages. In the same
H
manner, a digital medical network should reliably transfer a few bytes to megaĆ
bytes of data.
The postal system employs different methods of transportation to move the mail
in an efficient and cost effective manner, including people, trucks, trains and airĆ
planes. In the same way, digital medical networks should integrate different
transmission technologies to get the job done:
D
Within the hospital, digital medical networks may support different types of
Local Area Networks (LANs). For example, Ethernet, Fiber Distributed
Data Interface (FDDI), Digital Links, Dial-up circuits, etc.
D
When communicating outside a hospital, a digital medical network should
integrate Wide Area Networks (WANs) links. These links are in general proĆ
vided by regional or national telecommunication carriers who use a comĆ
bination of terrestrial, microwave and satellite technologies. A wide range
of service and speeds are available ranging from kilobit per second phone
lines to megabit per second leased lines and switched high speed services.

When digital medical devices need to “get the message across”, they communicate using the
same steps as the businesses of the postal system. The sending and receiving digital medical
devices should match at all levels of networking to guarantee efficient and reliable delivery
of data. The three layers of networking and the application they support are defined
immediately following Illustration 2–3.
ILLUSTRATION 2-3
H The application Transactions and Database are like the contents of a letter writĆ
ten in the native language. They are specific to each device, just as the usage of
the contents of a letter is specific to each reader and writer. The DICOM v3.0
Standard only addresses the network communications functions and data necesĆ
sary to support the applications. It does not specify the internal design of the deĆ
vice.
H The Application Message Exchange layer is similar to the translated letter. Using
DICOM v3.0, this layer allows nonĆcompatible platforms and applications to
communicate by defining common protocols and formats which support such feaĆ
tures as image transfer, database queries and retrieval of images/text related inĆ
formation.
H The Logical Networking layer is similar to the letter's packaging and labeling.
This layer defines how the message will be managed by the network and guaranĆ
tees reliable delivery within a hospital and remote hospitals. The Logical NetĆ
working layer shields the Application Message Exchange layer from physical
network technologies.
H The Physical Networking layer is similar to the trucks, trains and airplanes which
transport the letter. It is the physical medium (i.e. cabling) and its access methods
(access hardware and intermediate switches) such as Ethernet, FDDI, etc., which
exchanges the bits of data. The Physical Networking layer should support a
choice of options in order to address, in a cost effective manner, the various perĆ
formance requirements of the Logical Networking layer.
The Logical and Physical Networking layers must work together to support the Application
Message Exchange layer. To guarantee interoperability between devices, one approach
must be specified for each layer. The selection of these choices establishes a network
architecture.
Networking support is an integral part of any digital medical device. The Physical Network
which externally links the device is a small component of what is required for devices to
actually interoperate. The Logical Networking and Application Message Exchange
functions which are integrated into the medical devices play a role transparent to the user,
but fundamental to information exchange.

In the Logical Networking Layer the ID/Net architecture uses DICOM UL protocol

(TCP/IP). TCP is a robust protocol which guarantees reliable delivery of the application
messages. IP provides mechanisms which support the routing of data within a hospital or to
remote hospitals over a variety of physical networks. The ID/Net Physical Networking
Layer generally relies on Ethernet v2.0 as the Datalink and Physical Network Layer. Other
physical network technologies may be combined with Ethernet v2.0 (e.g. FDDI or Wide
Area Networks (WAN’s)).
It should be noted that TCP, IP, and Ethernet are not specific to the DICOM standard and are
multi-industry standards implemented in off-the-shelf commercial products. The DICOM
Upper Layers (UL) and the DICOM Application Layer are specific to the DICOM standard.
The DICOM Application Layer is introduced in more detail in section 3.

SECTION 3 - 3-1
OVERVIEW
This section of the document describes some of the fundamental concepts and models which
are used by the Application layer standardized by DICOM v3.0 and used by ID/Net
Implementations. DICOM v3.0 uses Object Oriented Design concepts and the OSI
Reference Model.
All parts of the DICOM v3.0 standard were unanimously approved in October of 1993. Part
10 of the DICOM Standard – Media Storage and File Formats, as well as additional parts
which are under development as of early 1994, are not discussed in this section.
The reader interested in a complete presentation of these concepts should refer to the
DICOM v3.0 standard. The last part in this section provides an overview of the nine DICOM
v3.0 Parts.

CONFORMANCE STATEMENTS
A DICOM v3.0 Conformance Statement is available for every piece of GE Imaging
Equipment having an ID/Net Interface (as is required by DICOM). The Conformance
Statement explicitly states the network capabilities and options implemented by that
device. For example, a Conformance Statement identifies which Information Object
Definitions (MR image, Patient/Study (RIS) object, etc.) may be sent and/or received. It
also identifies which Service Classes have been implemented (Storage, Query/Retrieve,
Print, etc.).
The purpose of the Conformance Statement is to define the capabilities of a specific device
and allow the reader to determine what exact functionality is available. That is,
Conformance Statements allow implementations to assess the level of interoperability
between two DICOM compliant devices.
3-3
DICOM V3.0 APPLICATION LAYER CONCEPTS
An Application Entity (AE) is an OSI Application Layer function which includes the
mechanisms by which applications exchange information on a network. The basic concepts
of an Application Entity, as used in the DICOM v3.0 standard, are described in this section
(see Ill. 3–1 for a pictorial representation of the DICOM Application Entity).
The DICOM model is based on an object-oriented model. Object-oriented modeling uses
abstract data objects (e.g., the definition of MR images, CT images, etc.) to represent a class
of real-world objects. Object-oriented modeling also defines generic “methods” (e.g.,
Store, Delete, Create, Get, etc.) which act upon the data objects. The combination of a
method and a data object being used by two peer AEs over an association constitutes an
instance of communication. Illustration 3–1 shows the relationship of the DICOM objects
model.

An AE uses the following concepts:

2.. DICOM Message Service Element Services (generic methods)
3.. Service Object Pair (SOP) Classes (the method and data object combined)
4.. Service Classes (a set of related SOP Classes)
5.. Association Negotiation (negotiate how data will be encoded and the type of data
to be exchanged)
Each of these concepts is defined in further detail in sections 3–3–1 through 3–3–5.
3-3-1
Information Object Definition
An Information Object Definition (IOD) is the specification used to define an abstract data
object (the information to exchange). The goal of an IOD is to provide an unambiguous
specification about related pieces of information. IODs do not represent a specific instance
of the data object, but rather a class of similar data objects which have the same properties.
IODs provide the mechanisms to specify data objects such as images (e.g., MR, CT, NM,
etc.) and also image related data objects such as curves, overlays, Radiology Information
System (RIS) information, etc.
3–2
GE Medical Systems
Introduction to the Integrated – Dicom/Network V3.0
REV 0
Conformance Statement 2118780
In DICOM an IOD consists of an Entity Relationship Model, information entities, modules,
and attributes. The content of an IOD is similar to a memo. A memo consists of words
(called attributes), sentences (a set of related words, called modules), paragraphs (a set of
related sentences, called information entities), and finally the memo (a set of related
paragraphs, described by an Entity Relationship Model).
3-3-2
DICOM Message Service Element (DIMSE) Services
Specifying an IOD is key for communication. However, it is not sufficient. Services
(methods) which operate on IODs need to be standardized. DICOM defines a set of generic
services (such as Store, Create, Delete, Get, etc.) which act upon instances of an IOD. These
services are called the DICOM Message Service Element (DIMSE).
3-3-3
Service Object Pair (SOP) Class
The coupling of one or more DIMSE Services with one specific IOD results in a Service
Object Pair Class (SOP Class). A SOP Class specification contains the rules which are
applied to the DIMSE Services and a related IOD. A SOP Class is equivalent to an “object
class” in the object-oriented model (the data plus the methods).
A SOP Class is the key specification building block for the successful communication
between two AEs. However, like the IOD, the SOP Class does not represent a specific
instance of communication. When a specific instance of communication does occur it is
defined as a SOP Instance. SOP Instances are used to represent real-world occurrences of
images, studies, patients, etc.
The analogy of a sentence can be used to describe the MR Storage SOP Class. The IOD acts
as the noun (an MR image). The DIMSE Service acts as the verb (Store). The SOP Class is
similar to a generic sentence (Store an MR image). The SOP Instance is similar to a specific
sentence (Store this MR image).
3-3-4
Service Class
A Service Class represents a specific function which is to be accomplished by peer AEs and
is defined by a set of related SOP Classes. For example, the features needed to query for
image information and to retrieve the actual image data are very closely related. To achieve
these features two SOP Classes are required, one to gather image information (query) and
one to get the image data (retrieve). The Query/Retrieve Service Class combines these
related SOP Classes into one Service Class.
The Service Class defines two roles which are used by communicating AEs, the Service
Class User (SCU) and Service Class Provider (SCP). These roles are based on the
“client/server model”. The SCU acts as the “client” while the SCP acts as the “server”. For
example, for the Storage Service Class, the SCU acts as the image send device while the SCP
acts as the image receive device.
3-3-5
Association Negotiation
Association establishment is the first phase of communication between peer AEs. The AEs
use the association establishment to negotiate how data will be encoded and the type of data
to be exchanged. Some of these negotiated parameters include Application Context,
Abstract Syntaxes, Transfer Syntaxes, and Application Association Information.
3–3
GE Medical Systems
Introduction to the Integrated – Dicom/Network V3.0
REV 0
Conformance Statement 2118780
The method of negotiation used in DICOM v3.0 is fairly simple. The device which initiates
the association proposes a list of possible options for each negotiated parameter. The
initiating device must be capable of supporting all of the options which it proposes. The
responding device selects which of the options it can support and returns this information to
the initiating device. This commonly agreed upon set of options is then available on the
corresponding association.
3-3-6
Example of AE Concepts
Following is an example of two systems which need to send/receive an MR image. This
example illustrates how DICOM is used to achieve this image exchange.

The MR Image IOD contains the Attributes which describe the complete set of data needed
to define the image. Some of the Attributes are Patient Name, Date of Scan, MR
Acquisition Type, Echo Time, Pixel Data, etc. Associated Attributes are grouped into
Modules. Modules contain the exact definition of each Attribute, including whether the
Attributes are required or optional and the rules of how these Attributes are related. A few
of the Modules are: Patient Identification Module, Image Pixel Module, Overlay Plane
Module, Lookup Table Module, etc. Associated Modules are grouped into Information
Entities. The key Information Entities include Patient, Study, Series, Equipment and
Image. As an example, the Image Information Entity includes the Image Pixel Module,
Overlay Plane Module, and the Lookup Table Module. The relationship of the Information
Entities is described by an Entity Relationship Model (see Ill. 3–2 for an example of an
Entity Relationship Model and DICOM Standard Part 3, section 5 for information on how to
interpret Entity relationship diagrams).

Conformance Statement 2118780
To determine how to couple the MR Image IOD and the C–STORE DIMSE Service each
device must understand the MR Storage SOP Class. In this example, only one DIMSE
Service is coupled with the MR Image IOD. However, other examples may include multiple
DIMSE Services coupled with one IOD.
The MR Storage Service Class is one of the SOP Classes specified by the DICOM Storage
Service Class. Each AE must understand which role it wishes to play for the MR Storage
SOP Class. The MR Scanner, which is sending the image, will act as the Storage Service
Class User (SCU). The Workstation, which is receiving the image, will act as the Storage
Service Class Provider (SCP).
To establish an Association between the two devices so the image may be sent, both AE’s
must understand the negotiation process. Two of the key parameters which will be
negotiated during Association Establishment are the Abstract Syntax and Transfer
Syntax. The Abstract Syntax identifies the SOP Class. In this example, the Abstract Syntax
is the MR Storage SOP Class (i.e., the MR Image IOD and the C–STORE DIMSE Service).
The Transfer Syntax identifies the type of pixel data encoding which will be used to send this
image, e.g., compressed or uncompressed pixel data.
In this example, the MR Scanner may initiate the Association by proposing several Abstract
and Transfer Syntaxes. The responding Workstation will identify the Syntaxes it can
support in its response to the MR Scanner.
3-3-6-1
Communication Scenario
Now lets go through the order that the steps occur in the actual transmission of the image.
The MR Scanner first initiates an association to the Workstation. It offers an Abstract
Syntax which represents the MR Storage SOP Class with two Transfer Syntaxes,
compressed or uncompressed pixel data. The Workstation responds by accepting the MR
Storage SOP Class and selecting the uncompressed Transfer Syntax (it could not support
compression). The association is now established.
The MR Scanner constructs the image per the MR IOD and uses the C–STORE DIMSE
Service to send that IOD. The result will form a message including a command (C–STORE)
and a Data Set (the MR IOD encoded Attributes). The actual image or MR Image SOP
Instance is identified by a unique identifier or UID (see section 3–4) .
The Workstation receives this MR Image SOP Instance and stores the information in it’s
database. The Workstation returns a “successful” response using the STORE DIMSE
Service. The image has now been successfully received.
At this time the MR Scanner may send more images or release the association.
Note: The above example illustrates a simple transfer of images. If both the MR Scanner
and the Workstation had implemented additional SOP Classes, such as Query/Retrieve,
these features could also be used on the same association.

UNIQUE IDENTIFIERS (UIDS)
Unique Identifiers (UIDs) provide the capability to uniquely identify a wide variety of
items. It guarantees uniqueness across countries, sites, vendors and equipment. This
scheme is used to uniquely identify items such as Service Object Pairs (SOP) Classes,
images, instances, network negotiation parameters, etc.

Conformance Statement 2118780
The UID identification scheme is based on the OSI Information Object as defined by the ISO
8824 standard. All UIDs, used within the context of the DICOM Standard, are based upon
registered values as defined by ISO 9843-3 to ensure global uniqueness.
There is a root portion of the UID which uniquely identifies GE Medical Systems. The root
is registered with ISO and therefore guarantees that GE-specific UIDs are unique among
vendors.
Per the DICOM v3.0 standard, three types of UID values are used:
1.. The DICOM UID values which are defined in the DICOM Standard (such as
SOP class UIDs).
2.. GEĆspecific UID values which are defined in the ID/Net DICOM Conformance
Statement for GE products (such as product Implementation Class UID's).
3.. GE-specific UID values dynamically generated by GE product implementaĆ
tions (such as Image SOP Instance UIDs).

RELATIONSHIP OF CONCEPTS TO THE PARTS OF THE DICOM V3.0 STANDARDS
DICOM v3.0 is comprised of nine Parts which were balloted and approved in October, 1993.
As of early 1994, three additional Parts related to Media Storage and File Format were
placed under review. The nine Parts of the DICOM v3.0 Standard and the areas which are
covered are:
Introduction and Overview
Conformance Requirements
Includes requirements for accurately writing a DICOM Conformance
Statement.
Information Objects Definitions
Includes IODs for MR, CT, Ultrasound, Nuclear, etc. It also includes IOD's
for Network Filming and Imaging Study Management (often called HIS/RIS
Interfacing).
Service Classes Specifications
Includes definitions of Service Class concepts, the SCU/SCP roles, and
definitions of Service Classes (i.e. Image Storage, Query/Retrieve,
Network Print, Study Management, Results Management, etc.).
Data Structure and Encoding
Includes DICOM data set structure, Data Element encoding rules, value
encoding definitions (e.g., short string, unsigned short int, etc.), Attribute
types, UID encoding rules and registration, and Transfer Syntax
specifications. The support of JPEG lossless compression is also fully
specified.
Data Dictionary
Includes Element list which is made up of Attribute Names and descriptions,
Data Element Tags (Group and Element numbers), Value Representations
and Multiplicity.
Message Exchange
Includes association negotiation information and structures, DIMSE
operation and notification rules and DIMSE service and protocol
definitions (e.g., CĆSTORE, CĆECHO).

DEFINITIONS
Many of the terms defined here are used in sections 2 and 3 of this document and in the
ID/Net DICOM Conformance Statement of each GEMS product.
Abstract Syntax: The Abstract Syntax identifies the Service/Object Pair (SOP) Class
which is used when two peer DICOM Application Entities communicate. The Abstract
Syntax is negotiated at the time of Association Establishment.

ACR-NEMA: A standards body sponsored by the American College of Radiology (ACR)
and the National Electrical Manufacturers Association (NEMA).
Application Context: An Application Context is a name which is used to identify the use of
the DICOM Application Services over an association. It is negotiated between two peers
during association establishment.
Application Entity (AE): An Application Entity is an OSI Application Layer function
which includes the mechanisms by which applications exchange information on a network.
Oversimplistically, an AE is a program which contains network communications
capabilities and which runs on a computer.
Association Establishment: An Association represents a level of connectivity
between to AEs. An Association Establishment is the first phase of communication
between two peer DICOM AEs. The two peers use this method to negotiate some
communication parameters such as Abstract Syntax, Transfer Syntax, etc.
Attributes: Attributes are properties which describe an Information Object Definition. An
Attribute is identified by a name and its associated Data Element Tag (group and element
number).
Conformance Statement: The Conformance Statement states which options and features
of DICOM have been implemented by a specific product (e.g. which IOD’s, which Service
Classes, etc.). It specifies in technical detail how a particular implementation meets the
conformance requirements set forth by DICOM v3.0. Every device which claims DICOM
conformance must openly publish a DICOM conformance statement, written in the format
specified by DICOM Part 2.
Data Element: A Data Element is an encoded Attribute and is part of a Data Dictionary.
The Data Element Tag is used to uniquely identify the piece of information within the
Dictionary. An Element Number is combined with a Group Number to make up a tag. For
example, Study (Exam) Number is Group 20 Element 10. The group and element number
tag are encoded in the Data Set (and, hence, the data stream.)
DICOM: The acronym of the final version of the standard produced by the ACR-NEMA
committee is officially called: Digital Imaging and Communications in Medicine (DICOM
v3.0), and was unanimously approved in October 1993.

DIMSE: DICOM Message Service Element. The DICOM v3.0 Standard defines the
services and protocols used by an Application Entity to exchange messages. These services
and protocols define the DICOM Message Service Element (DIMSE). DIMSE defines
generic “operations” (such as Store, Move, Find, Get, etc.) which can be used in specifying
SOP Classes. DIMSE are defined in DICOM v3.0 Part 7.
Element: Informal term used to reference a Data Element.
Full Fidelity Storage: The characteristic of a receiving device to be able to receive and
store all attributes, including private attributes, specified for a given Image Information
Object Definition.
Group: A Group is a collection of data elements within a message and is part of a Data
Dictionary Tag (see Tag).
Information Entity: An Information Entity is a subset of an Information Object Definition
(e.g., CT image or MR image). It is a group of related Modules.
Information Object: Informal term used to reference an Information Object Definition.
Information Object Definition (IOD): An IOD is a data model which is an abstraction of
real-world information (e.g., an MR Image or CT Image) and which is acted upon by one or
more DIMSE operations. An IOD consists of a data model describing the interpretation of
the information and the attributes which define it.
Module: A Module is a set of Attributes within an Information Object which are logically
related to each other. For example, the “Patient Identification Module” may be defined by
the following attributes: Patient Name, Patient ID, and Patient Birthdate, and Patient Sex.
Service Class: A Service Class defines a specific function which is to be accomplished by
connecting AEs. A Service Class specifies a set of one or more Service/Object Pairs (SOP)
which perform a function across a network and provide interoperability between two
application entities. Examples of a Service Class include image storage, query/retrieve, etc.
Service Class Provider (SCP): A Service Class Provider acts in a “server” role to the
Service Class during a network communications exchange. An SCP performs operations
requested by an SCU and may also provide notifications to the SCU. An example of a
Storage Service Class Provider would be the image storage device. In this case, the image
storage device is storing the image as requested by the SCU.
Service Class User (SCU): A Service Class User acts in a “client” role to the Service Class
during a network communications exchange. An SCU requests that an SCP perform
operations. An example of a Storage Service Class User would be the image send device.
In this case, the image send device will send an image by requesting the SCP to store that
image.
Service/Object Pair (SOP) Class: A SOP Class is defined by the union of an IOD and a
DIMSE Service Group. The SOP Class definition contains the rules and semantics which
may extend or restrict the definitions of the DIMSE Service Group or the IOD attributes. A
DICOM Application Entity may support one or more SOP Classes. Each SOP Class is
identified by a SOP Class UID.
SOP Instance: A representation of a specific occurrence of a SOP class.

Tag: The Tag is used to uniquely identify information within a Data Dictionary. A Group
Number is combined with an Element Number to make up a tag. For example, Study
(Exam) Number is Group 20 Element 10. The group and element number tag are encoded in
the data stream. In v2.0, the Group was used to convey semantic information (e.g., Group 10
is Image Information). However, in DICOM v3.0 the Group semantic information has been
replaced with the Module concept.
Transfer Syntax: The Transfer Syntax represents the type of data encoding which is used
when two peer DICOM Application Entities communicate. The Transfer Syntax is
negotiated at the time of Association Establishment. Examples of Transfer Syntaxes are
Little Endian, Big Endian, JPEG lossless compression, etc.
Unique Identifier (UID): A Unique Identifier is a method which is used to create a globally
unique ASCII-numeric string. It guarantees uniqueness across multiple countries, sites,
vendors and equipment. The UID encoding method which is used in DICOM v3.0 is ISO
compliant. A few examples for uses of UIDs are SOP Class UID, Image UID, network
negotiation parameters, etc.
Upper Layer (UL): The Upper Layer is part of the DICOM Logical Network Layer of
software. The Upper Layer performs such functions as the Association Establishment
(including Abstract and Transfer Syntax negotiation), the encoding and decoding of a
DICOM message stream, etc.

This document specifies the DICOM v3.0 implementation. It is entitled:
ADVANTX DLX
Conformance Statement for DICOM v3.0 (ID/Net v3.0)
Direction ........# 2142506–100
This Conformance Statement documents the DICOM v3.0 Conformance Statement and Technical
Specification required to interoperate with the GEMS ID/Net v3.0 network interface. Introductory
information, which is applicable to all GEMS ID/Net v3.0 Conformance Statements, is described in the
document:
Introduction to the Integrated DICOM/Network v3.0 (ID/Net v3.0)
Conformance Statement
Direction: 2118780.
This Introduction familiarizes the reader with DICOM terminology and general concepts. It should be
read prior to reading the individual products’ ID/Net v3.0 Conformance Statements.
The ID/Net v3.0 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 v3.0 Part 8 standard.
For more information including Network Architecture and basic DICOM concepts, please refer to the
Introduction.
For the convenience of software developers, there is “collector” Direction available. By ordering the
collector, the Introduction described above and all of the currently published ID/Net v3.0 Product
Conformance Statements will be received. The collector Direction is:

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 v3.0 Standards and with the
terminology and concepts which are used in those Standards.
If readers are unfamiliar with DICOM v3.0 terminology they should first refer to the document listed
below, then read the DICOM v3.0 Standard itself, prior to reading this Conformance Statement document.

SCOPE AND FIELD OF APPLICATION
It is the intent of this document, in conjunction with the Introduction to the Integrated DICOM/Network
v3.0 (ID/Net v3.0) Conformance Statement, Direction: 2118780, to provide an unambiguous specification
for GEMS ID/Net v3.0 implementations. This specification, called a Conformance Statement, includes a
DICOM v3.0 Conformance Statement and is necessary to ensure proper processing and interpretation of
GEMS medical image data exchanged using DICOM v3.0. The GEMS ID/Net v3.0 Conformance
Statements are available to the public.
The reader of this Conformance Statement should be aware that different GEMS
devices are capable of using different Information Object Definitions. For example, a GEMS CT Scanner
may send images using the CT Information Object, MR Information Object, Secondary Capture Object,
etc.
Included in this Conformance Statement are the Module Definitions which define all data elements used
by this GEMS ID/Net v3.0 implementation. If the user encounters unspecified private data elements while
parsing a GEMS Data Set, the user is well advised to ignore those data elements (per the DICOM v3.0
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 GEMS devices.

IMPORTANT REMARKS
The use of these Conformance Statements, in conjunction with the DICOM v3.0 Standards, is intended to
facilitate communication with GE imaging equipment. However, by itself, it is not sufficient to ensure
that inter–operation will be successful. The user (or user’s agent) needs to proceed with caution and
address at least four issues:
D
Integration - The integration of any device into an overall system of interconĆ
nected devices goes beyond the scope of standards (DICOM v3.0), and of this
introduction and associated Conformance Statements when interoperability
with non-GE equipment is desired. The responsibility to analyze the applicaĆ
tions requirements and to design a solution that integrates GE imaging equipĆ
ment with nonĆGE systems is the user's responsibility and should not be
underestimated. The user is strongly advised to ensure that such an integration
analysis is correctly performed.
D
Validation - Testing the complete range of possible interactions between any GE
device and nonĆGE devices, before the connection is declared operational,
should not be overlooked. Therefore, the user should ensure that any nonĆGE
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 nonĆGE 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.

D
Future Evolution - GE understands that the DICOM Standard will evolve to
meet the user's growing requirements. GE is actively involved in the developĆ
ment of the DICOM v3.0 Standard. DICOM v3.0 will incorporate new features
and technologies and GE may follow the evolution of the Standard. ID/Net v3.0
is based on DICOM v3.0 as specified in each ID/Net DICOM Conformance
Statement. Evolution of the Standard may require changes to devices which have
implemented DICOM v3.0. In addition, GE reserves the right to discontinue or
make changes to the support of communications features (on its products) reĆ
flected on by these ID/Net DICOM Conformance Statements. The user should
ensure that any nonĆGE provider, which connects with GE devices, also plans for
the future evolution of the DICOM Standard. Failure 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.
D
To be kept informed of the evolution of the implementation described in this
document, the User should register on the GE Internet Server, accessible via
anonymous ftp, by entering his e-mail address (GE Internet Server Address:
ftp.med.ge.com, 192.88.230.11)
D
Interaction - It is the sole responsibility of the nonĆGE provider to ensure that
communication with the interfaced equipment does not cause degradation of GE
imaging equipment performance and/or function.

The dlx_root Application Entity (AE) is an application which handles DICOM protocol communication.
dlx_root AE is automatically brought up when the Digital Angiographic system (DLX) is powered on.
All remote DICOM’s AE must be manually configured on the DLX, usually at the software installation
time, by a GE field engineer.
There are 3 local real world activities: Copy Image (CI), Get Worklist (GW) and Verification which can
cause the dlx_root AE to initiate a DICOM association.
CI consists of an operator selecting one or several images to be sent on one or several Remote System(s).
Selection of Images is done from the Operator console screens (known as BROWSER and VIEWER);
selection of Remote Systems and visualisation of the status of the transfer is done on a specific menu
(known as TRANSFER menu) . Remote Workstation can be any DICOM compliant WorkStation.

GW consists of an operator request for the transfer of a list of Patient/Exam entries from a predefined
remote HIS/RIS system. There is no query key set for subselection of items. The current implementation
asks for all data prepared for transfer to DLX. The remote workstation can be any DICOM compliant
HIS/RIS system supporting XA modality.
Verification consists of an operator request for the verification of the availability of a remote station.

2-2-1-2-1-2-1SOP Specific Conformance Statement for Image Storage SOP Class
This implementation performs a single C–STORE operation over an association.
If the AE doesn’t receive a C–ECHO confirmation, this implementation will terminate the association.
The transfer is considered as failed, no association for C–STORE will be attempted.
Upon receiving a C–ECHO confirmation containing an Error, Refused or Warning status, this
implementation will consider the result as OK. This is because the only purpose of the C–ECHO is to
check that the remote AE responds, whatever is the C–ECHO status. This implementation doesn’t require
that remote AE implements Verification SOP class as a SCP.

REV 6
Dicom Conformance Statement 2142506–100
Upon receiving a C–STORE confirmation containing an Error or a Refused status, this implementation
will terminate the association. The current C–STORE is considered as failed.
Upon receiving a C–STORE confirmation containing a Warning Status, this implementation will treat it as
an Error or Refused response.
Each C–STORE operation supports an “ Association Timer ”. This timer starts when the association
request is sent and stops when the association is established. This timer is set to 60 seconds.
Each C–STORE operation supports an “ Operation Inactivity Timer ”. This timer starts once a C–STORE
request has been issued and stops once a C–STORE confirmation has been received. This Timer is set to 60
minutes.
If any of the 2 timers expires, the connection is closed and the operation is considered as failed.
2-2-1-2-2
Real-World Activity "Get Worklist"

GE Medical Systems
REV 6
Dicom Conformance Statement 2142506–100
If the AE does not receive a C–ECHO confirmation, this implementation will terminate the association.
The Worklist request is considered as failed.
Upon receiving a C–ECHO confirmation containing an Error, Refused or Warning status, this
implementation will consider the result OK. This is because the only purpose of the C–ECHO is to check
that the remote AE responds.
Each C–ECHO and C–FIND operation supports an “Association Timer”. This timer starts when the
association request is sent and the stops when the association is established. This timer is set to 30 seconds.
The C–ECHO operation supports an “Operation Inactivity Timer”. This timer starts when the C–ECHO
request is sent and it stops when the C–ECHO response is received. This timer is also set to 30 seconds.
Upon receiving a C–FIND response containing an error status this implementation will terminate the
association issuing a close request. The current C–FIND is considered as failed.
Each C–FIND operation supports an “Operation Inactivity Timer”. This timer starts when the C–FIND
request is sent and it stops when the C–FIND final response received. This timer is set to 60 seconds.
If any of the timers expires, the connection is closed and the operation is considered as failed.
Badly formatted C–FIND response(s) from the SCP will result in the initiatiation of a C–FIND cancel
request. In the dlx_root AE, the C–FIND cancel operation is not implemented as an additional operator
choice.
On completion of operation the dlx_root AE places the status (flag) of the final Worklist update operation
on DLX into the Abort flag of the close association request. That way the Worklist provider can get a final
success feed back of the complete HIS/RIS data transfer operation. This flag setting doesn’t change the
basic DICOM association management functionality.
2-2-1-2-3
Real–world Activity “Verification”
2-2-1-2-3-1
Associated Real-World Activity
The operator selects a destination by selecting an host in the TRANSFER menu (by default the last
selected host is active).
Then he presses on the “host verification” button or on the “worklist verification”button if he wants to test
the worklist server.
These operations will cause

XA IMAGE IOD MODULE TABLE
Within an entity of the DICOM v3.0 XRAY Angio Image Information Object Definition, attributes are
grouped into related set of attributes. A set of related attributes is termed a module. A module acilitates the
understanding of the semantics concerning the attributes and how the attributes are related with each other.
A module grouping does not infer any encoding of information into datasets.
Table 2 identifies the defined modules within the entities which comprise the DICOM v3.0 XRAY Angio
Image Information object Definition. Modules are identified by Module Name.
See DICOM v3.0 Part 3 for a complete definition of the entities, modules, and attributes.

SC IMAGE IOD MODULE TABLE
Within an entity of the DICOM v3.0 XRAY Angio Image Information Object Definition, attributes are
grouped into related set of attributes. A set of related attributes is termed a module. A module facilitates the
understanding of the semantics concerning the attributes and how the attributes are related with each other.
A module grouping does not infer any encoding of information into datasets.
Table 5–2 identifies the defined modules within the entities which comprise the DICOM v3.0 XRAY
Angio Image Information object Definition. Modules are identified by Module Name.
See DICOM v3.0 Part 3 for a complete definition of the entities, modules, and attributes.

INTRODUCTION
This section specifies the use of the Basic Worklist Management Information Objects to transfer the
Worklist from the Information System to the Application Entity where the task is performed.
5-1
WORKLIST INFORMATION MODEL IMPLEMENTATION
This section defines the implementation of the Basic Worklist Information Object. It refers to the DICOM
V3.0 Standard, Basic Worklist Management – Supplement 10 (August 11, 1995) to Part 3 (Information
Object definition).

The Entity–Relationship diagram for the Basic Worklist Management interoperability schema is shown in
Illustration 5–1. In this figure, the following diagrammatic convention is established to represent the
information organization :
• each entity is represented by the gray rectangular box.
• each relationship is represented by the white rectangular box.
• the fact that a relationship exists between the two entities is depicted by lines connecting the
corresponding entity boxes to the relationship boxes.
5-2-1
Entities Description
Refer to DICOM Standard Supplement 10 (August 11, 1995) to Part 3 (Information Object Definitions) for
a description of the entities contained within this Information object.
5-3
BASIC WORKLIST INFORMATION MODULE TABLE
Within an entity of the DICOM v3.0 Basic Worklist Information Object Definition, attributes are grouped
into related set of attributes. A set of related attributes is termed a module. A module facilitates the
understanding of the semantics concerning the attributes and how the attributes are related with each other.
A module grouping does not infer any encoding of information into data sets.
Table 2 identifies the defined modules within the entities which comprise the DICOM v3.0 Basic Worklist
Management Information Object. Modules are identified by Module Name.
See DICOM v3.0 Part 3 for a complete definition of the entities, modules and attributes.
