3 1. DICOM COMFORMANCE STATEMENT OVERVIEW POP-Net Essential supports display of DICOM image objects obtained over the network, from interchange media, or from PS 3.10 files loaded from the local file system. POP-Net Essential supports querying a remote system for a list of DICOM objects that may then be retrieved to the local system. It also supports sending locally loaded images across the network to another system. Most storage SOP Classes defined as of DICOM 2004 can be received, stored and transmitted by POP-Net Essential, but some may not be loaded and viewed. All single and multi-frame with grayscale and color images may be displayed. Both hierarchical and relational queries are supported.

12 3 INTRODUCTION 3.1 Revision History Document Version Date of Issue Author Description 4.0 February 9, 2005 M. Kobayashi Revised per DICOM 2004 Part Audience This document is intended for hospital staff, health system integrators, software designers or implementers. It is assumed that the reader has a working understanding of DICOM. 3.3 Remarks DICOM, by itself, does not guarantee interoperability. However, the Conformance Statement facilitates a first-level validation for interoperability between different applications supporting the same DICOM functionality. This Conformance Statement is not intended to replace validation with other DICOM equipment to ensure proper exchange of information intended. The scope of this Conformance Statement is to facilitate communication between the POP-Net Essential and other DICOM systems. The Conformance Statement should be read and understood in conjunction with the DICOM Standard [DICOM]. However, by itself it is not guaranteed to ensure the desired interoperability and a successful interconnectivity. The user should be aware of the following important issues: The comparison of different Conformance Statements is the first step towards assessing interconnectivity between POP-Net Essential and other DICOM conformant equipment. Test procedures should be defined to validate the desired level of connectivity. Page 12

Conceptually the network services may be modeled as the following separate AEs, though in fact all the AEs share a single (configurable) AE Title: ECHO-SCP, which responds to verification requests STORAGE-SCP, which receives incoming images and other composite instances STORAGE-SCU, which sends outbound images and other composite instances FIND-SCU, which queries remote AEs for lists of studies, series and instances MOVE-SCU, which retrieves selected studies, series or instances Page 14

15 PRINT-SCU, which sends outbound images and other composite instances to a printing device Functional Definitions of AE s ECHO-SCP ECHO-SCP waits in the background for connections, will accept associations with Presentation Contexts for SOP Class of the Verification Service Class, and will respond successfully to echo requests STORAGE-SCP STORAGE-SCP waits in the background for connections, will accept associations with Presentation Contexts for SOP Classes of the Service Class, and will store the received instances to the local database where they may subsequently be listed and viewed through the user interface STORAGE-SCU STORAGE-SCU is activated through the user interface when a user selects instances from the local database or a DICOMDIR, or the currently displayed instance, and requests that they be sent to a remote AE (selected from a pre-configured list) FIND-SCU FIND-SCU is activated through the user interface when a user selects a remote AE to query (from a pre-configured list), then initiates a query. Queries are performed recursively from the study through the series and instance levels until all matching instances have been listed MOVE-SCU MOVE-SCU is activated through the user interface when a user selects a study, series or instance for retrieval. A connection to the remote AE is established to initiate and monitor the retrieval and the STORAGE-SCP AE receives the retrieved instances PRINT-SCU PRINT-SCU is activated through the user interface when a user selects instances from the currently displayed instances, and requests that they be printed by a remote AE (selected from a pre-configured list). Page 15

16 4.1.3 Sequencing of Real-World Activities All SCP activities are performed asynchronously in the background and not dependent on any sequencing. All SCU activities are sequentially initiated in the user interface, and another activity may not be initiated until the prior activity has completed. Page 16

When displaying an image in the viewing application, the newest Grayscale Softcopy Presentation State containing references to the image will be automatically applied and the GSPS Presentation Label and Presentation description will be displayed in the status bar. The user has the option to select any other Presentation States that also references the image. If no Presentation State references the image then no Presentation State will be applied by default. The Mask Subtraction transformation contained in Mask Subtraction Sequence (0028,6100) in Presentation State is also supported. Grayscale images in all of the Image SOP Classes listed in Table are supported as references from instances of the Grayscale Softcopy Presentation State SOP Class Presentation Context Acceptance Criterion STORAGE-SCP will always accept any Presentation Context for the supported SOP Classes with the supported Transfer Syntaxes. More than one proposed Presentation Context will be accepted for the same Abstract Syntax, if the Transfer Syntax is Page 25

26 supported, whether or not it is the same as another Presentation Context Transfer Syntax Selection Policies If offered a choice of Transfer Syntaxes in a Presentation Context, it will apply the following priority to the choice of Transfer Syntax: a. First encountered Transfer Syntax, if it is one of the Transfer Syntax s listed in Table or b. DICOM default Transfer Syntax, which is Implicit VR Little Endian. STORAGE-SCP will accept duplicate Presentation Contexts, that is, if it is offered multiple Presentation Contexts, each of which offers acceptable Transfer Syntaxes, it will accept all Presentation Contexts, applying the same priority for selecting a Transfer Syntax for each Response Status STORAGE-SCP will behave as described in Table when generating the C-STORE response command message. Table RESPONSE STATUS FOR STORAGE-SCP AND RECEIVE STORAGE REQUEST Service Status Further Meaning Error Code Behavior Success Success 0000 The Composite SOP Instance was successfully received. Refused Error Out of Resources Data Set does not match SOP Class A700 A900 Indicates that there was not enough disk space to store the image or resource to process storage.
