This document specifies the DICOM v3.0 implementation. It is entitled: EchoPAC version 6.3.6 Conformance Statement for DICOM v3.0 Direction 2256472-100 This DICOM Conformance Statement documents the DICOM v3.0 Conformance Statement and Technical Specification required to inter-operate with the GEMS network interface. Introductory information, which is applicable to all GEMS 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' GEMS Conformance Statements. The GEMS 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 GEMS Product Conformance Statements will be received. The collector Direction is: ID/Net v3.0 Conformance Statements Direction: 2117016 For more information regarding DICOM v3.0, copies of the Standard may be obtained by written request or phone by contacting: NEMA Publication 1300 North 17th Street Suite 1847 Rosslyn, VA 22209 USA Phone: (703) 841-3200 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 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 DICOM Conformance Statement document. Introduction to the Integrated DICOM/Network v3.0 (ID/Net v3.0) Conformance Statement Direction: 2118780 3

1.4 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 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 data exchanged using DICOM v3.0. The GEMS Conformance Statements are available to the public. The reader of this DICOM 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 DICOM Conformance Statement are the Module Definitions, which define all data elements, used by this GEMS 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. 1.5 IMPORTANT REMARKS The use of these DICOM 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 interconnected devices goes beyond the scope of standards (DICOM v3.0), and of this introduction and associated DICOM 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 an 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 v3.0 Standard. DICOM v3.0 will incorporate new features and technologies and GE may follow the evolution of the Standard. The GEMS protocol is based on DICOM v3.0 as specified in each 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) reflected on by these DICOM Conformance Statements. The user should ensure that any non-ge 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. To be informed of the evolution of the implementation described in this document, the User is advised to regularly check the GE Internet Server, accessible via anonymous ftp (GE Internet Server Address: ftp.med.ge.com, 192.88.230.11). Interaction - It is the sole responsibility of the non-ge provider to ensure that communication with the interfaced equipment does not cause degradation of GE imaging equipment performance and/or function. 4

2. NETWORK 2.1 INTRODUCTION This section of the DICOM Conformance Statement specifies the compliance to DICOM conformance requirements for the relevant Networking features for EchoPAC 6.3.6. 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. 2.2 IMPLEMENTATION MODEL 2.2.1 Application Data Flow Diagram The Basic and Specific Application models for this device are shown in the following illustration: 6

Screen Capture Image Store Association Initiation EchoPAC Remote Storage SCP Echo EchoPAC Association Initiation and Acceptance Remote Verification SCU/SCP Worklist Query EchoPAC Modality Worklist SCP Print Image Store Image Store Association Initiation EchoPAC Association Initiation EchoPAC Association Initiation EchoPAC Print Mgmt SCP Modality PPS SCP Storage Commitm. SCP Association Initiation DICOM Standard Interface There are five local real-world activities that occur in EchoPAC - Image Store, Screen Capture, Echo, Worklist Query and Print. 7

Image Store initiates a connection with the server, encodes one or more images and transmits the images to the server. If Modality Performed Procedure Step is configured, EchoPAC will send start and end exam messages. If Storage Commitment is configured and EchoPAC is not in DICOM mode, EchoPAC will send commitment request message and respond to answer from the server. Image Store is activated either pressing Export in Patient Home Screen, pressing Send patients in DICOM buffer or pressing DICOM in the View Images or View Buffer. If an error occurs during transmission the storage is terminated and an error message is posted to the user. Screen Capture initiates a connection with the server, encodes a DICOM image and transmits the images to the server. Screen Capture is activated pressing the Secondary Captured short-cut key. Screen Capture will only be activated if DICOM Storage SCP is selected as the target. If an error occurs during transmission the storage is terminated. Echo initiates a connection with the DICOM server, posts an Echo message and closes the connection. Echo also responds to Echo messages from an SCU. Worklist Query sends a query to a Worklist server with the search criteria entered in Worklist Screen. Print will send images from the print buffer to a DICOM Print server. 2.2.2 Functional Definition of AE's Application Entity EchoPAC supports the following functions: Initiates a DICOM association to send images. Encodes raw data images into DICOM images or load DICOM images from disk. Transmits DICOM images to the DICOM Storage SCP. Initiates a DICOM verification to assist in network diagnostics. Responds to DICOM verification requests from other devices. Initiates a DICOM worklist query to receive worklist info. Initiates a DICOM association to print images. Initiates a DICOM association to notify start of examination. Initiates a DICOM association to notify end of examination. Initiates a DICOM association to request storage commitment of images and responds to answer from server. 2.2.3 Sequencing of Real-World Activities Image Store: EchoPAC initiates a DICOM association with the selected archive device AE when the operator requests an image to be sent. The initial association negotiation list depends on the configuration setting. The association negotiation lists are described in 2.3.1.2.1.2. The images are then transferred to the Storage SCP (DICOM servers) using the C-STORE command. Multiple images are sent on the same DICOM Association according to the configuration of the connection in the Config Setup. For example, if the images are within one series and the reopening setting is series, study, patient or session, then all images 8

are sent on the same connection. If the reopening setting is image, then the connection is reopened between sending every image. In DICOM mode, reopening is not in effect. If the export is successful and Modality Performed Procedure Step in configured, EchoPAC will send the following Modality Performed Procedure Step messages: N-CREATE, N-SET with list of all exported (except imported DICOM images and Secondary Captures) images and an N-SET with the status COMPLETED. If the export is successful, Storage commitment is configured and EchoPAC is not in DICOM mode, EchoPAC will send the Storage Commitment message N-ACTION-RQ for all images in the export (except imported DICOM images and Secondary Captures). EchoPAC will then listen for N-EVENT-REPORT-RQ from the Storage commitment server and update the status of the sent commitment request. Screen Capture: EchoPAC initiates a DICOM association with the selected archive device AE when the operator requests an image to be sent. The initial association list depends on the configuration setting. The association negotiation list is described in 2.3.1.2.1.2. The images are then transferred to the server using the C-STORE command. Echo: An Echo is initiated in the Config Screen using the "Echo" button. The AE uses the C-ECHO to verify the communication path to a remote AE. Echo also responds to Echo messages from an SCU. Upon a DICOM association with a Verify message, Echo will respond to the client. Worklist Query: EchoPAC initiates a DICOM association to one specific SCP, using the C-FIND command to query and retrieve the worklist information. Print: EchoPAC s AE initiates a DICOM association with the selected printer AE when the operator presses the button for sending a print job to the printer. The AE uses the N-GET to retrieve an instance of the Printer SOP Class. The AE uses the N-CREATE to create a Basic Film Session SOP Instance. The AE uses the N-CREATE to create a Basic Film Box SOP Instance. The AE uses the N-SET to update the Basic Image Box IOD. The AE uses the N-ACTION (PRINT, Film Session Sop Instance) command to print the image. The AE uses the N-DELETE to delete the Film Box SOP Instance. 2.3 AE SPECIFICATIONS 2.3.1 EchoPAC AE Specification This Application Entity provides Standard Conformance to the following DICOM V3.0 SOP Classes as an SCU: SOP Class Name SOP Class UID Ultrasound Multi-frame Image Storage 1.2.840.10008.5.1.4.1.1.3.1 9

The maximum length PDU for an association initiated by EchoPAC is configurable. Maximum Length PDU Configurable from 4096 to 30000 The SOP Class Extended Negotiation is not supported. The user information Items sent by this product are: 10

Maximum PDU Length Implementation UID Implementation Version Name 2.3.1.1.2 Number of Associations The EchoPAC AE will initiate only one DICOM association at a time to perform an image store, or verify. The EchoPAC AE can have a maximum of two DICOM associations open simultaneously, one to send an image and one to respond to an Echo or Storage Commitment result. 2.3.1.1.3 Asynchronous Nature Asynchronous mode is not supported. All operations will be performed synchronously. 2.3.1.1.4 Implementation Identifying Information The Implementation UID for this DICOM v3.0 Implementation is: EchoPAC Implementation UID 1.2.840.113619.6.71 The Implementation Version Name for this DICOM v3.0 Implementation is: EchoPAC Implementation Version Name EchoPAC_6_3_6 Note: The Implementation Version Name and may change in the future without modification of this document. 2.3.1.2 Association Initiation Policy The EchoPAC AE attempts to establish a new association with a remote device due to five Real-World Activities: Image Store initiated by the operator for a specific image or group of images. Screen Capture initiated by the operator for a specific image or group of images. Verification, which verifies application level communication between peer DICOM AE s for service purposes. Worklist initiated by the operator for receiving worklist info. Print initiated by the operator for a specific image or group of images. 2.3.1.2.1 Real-World Activity A ( Image Store Operation) 2.3.1.2.1.1 Associated Real-World Activity Upon a request by the operator, images will be sent to a DICOM Storage SCP. If an error occurs during the transmission, the current association is released and a new association initiated. The maximum number of retries is configurable. 11

2.3.1.2.1.2 Proposed Presentation Context Tables The proposed transfer syntaxes depend on the configuration settings for reopening the connection if compression is not Default, in which case all syntaxes are proposed. If the reopening setting is equal to session, patient or study, the most advanced negotiation scheme is used. Then the connection is negotiated to allow for transfer of image objects using of different transfer syntaxes without reopening the connection to the Storage SCP. This means that images encoded with different compression schemes may be transmitted without reopening the connection. Not all Storage SCP devices handles this association policy properly, and verification of image handling is necessary before using this setting. If the Reopen Transmission is equal to series, the negotiation list contains only one instance of every SOP class UID, and the objects are negotiated using one compression setting. This means that images encoded using different SOP class UIDs (Secondary Captured, Ultrasound, Ultrasound MF) may be transmitted without reopening the Storage SCP connection, as long as the images are encoded using the same compression (uncompressed, RLE or JPEG) and the images are within one series. This association policy is normally supported by the Storage SCP devices. If the reopening setting is equal to image, only one SOP class UID and one image compression scheme is negotiated. In this case the Storage SCP connection is reopened between sending every images. This association policy may be used if the communication with the Storage SCP device is problematic using Reopen Transmission equal to series. 2.3.1.2.1.2.1 Reopen Transmission: session, patient or study The Proposed Presentation Context Table used when the Reopen Transmission is set to session, patient or study is: Presentation Context Table 1 - Proposed Abstract Syntax Transfer Syntax Role Extended Name UID Name List UID List Negotiation Secondary Capture Image Storage Secondary Capture Image Storage Secondary Capture Image Storage 1.2.840.10008.5.1.4.1.1.7 Explicit VR Little Endian Explicit VR Big Endian Implicit VR Little Endian 1.2.840.10008.5.1.4.1.1.7 Run Length Encoding, RLE 12 1.2.840.10008.1.2.1 1.2.840.10008.1.2.2 1.2.840.10008.1.2 SCU 1.2.840.10008.1.2.5 SCU 1.2.840.10008.5.1.4.1.1.7 JPEG Baseline 1.2.840.10008.1.2.4. 50 Ultrasound Image Storage 1.2.840.10008.5.1.4.1.1.6.1 Explicit VR Little Endian Explicit VR Big Endian Implicit VR Little Endian Ultrasound Image Storage 1.2.840.10008.5.1.4.1.1.6.1 Run Length Encoding, RLE 1.2.840.10008.1.2.1 1.2.840.10008.1.2.2 1.2.840.10008.1.2 SCU SCU 1.2.840.10008.1.2.5 SCU Ultrasound Image Storage 1.2.840.10008.5.1.4.1.1.6.1 JPEG Baseline 1.2.840.10008.1.2.4. 50 Ultrasound Multi-frame Image Storage Ultrasound Multi-frame Image Storage Ultrasound Multi-frame Image Storage 1.2.840.10008.5.1.4.1.1.3.1 Explicit VR Little Endian Explicit VR Big Endian Implicit VR Little Endian 1.2.840.10008.5.1.4.1.1.3.1 Run Length Encoding, RLE 1.2.840.10008.1.2.1 1.2.840.10008.1.2.2 1.2.840.10008.1.2 SCU SCU 1.2.840.10008.1.2.5 SCU 1.2.840.10008.5.1.4.1.1.3.1 JPEG Baseline 1.2.840.10008.1.2. 4.50 SCU

3. MEDIA STORAGE 3.1 INTRODUCTION This section of the conformance statement (CS) specifies the EchoPAC compliance to DICOM Media Interchange. It details the DICOM Media Storage Application Profiles and roles, which are supported by this product. EchoPAC is able to export raw data files or screen captured object to DICOM media, browse DICOM media or import SOP instances from DICOM media. 3.2 IMPLEMENTATION MODEL 3.2.1 Application Data Flow Diagram The Basic and Specific Application models for this device are shown in the following Illustration: ILLUSTRATION 3 1 SPECIFIC AE APPLICATION MODEL Image Store Screen Capture DICOM Browse EchoPAC AE FSC FSU FSR Media Storage Import The EchoPAC device has a local storage that is capable of containing various SOP instances. These may have been obtained by network or by removable media using other application entities. These instances are external to this conformance claim and the origin of the SOP instances is outside the scope of this claim. EchoPAC can initialize Media by acting as an FSC to create a new DICOM File-set on either 320 MB MOD, 640 MB MOD, 1.2 GB MOD, 2.4 GB MOD or Floppy. The SOP instances written to media must be one of the instances supported by EchoPAC. A pre-existing File-set will be updated with the information in DICOM files copied to media. 26
