Reason for Change Initial version Update document after review

Purpose and Intended Audience of this Document This document is a DICOM Conformance Statement for the DICOM Services of the IMPAX EE Mammography product. The user of this document is involved with system integration and/or software design. We assume that the reader is familiar with the terminology and concepts that are used in the DICOM 3.0 standard and the IHE Technical Framework. Readers not familiar with DICOM 3.0 terminology should first read the appropriate parts of the DICOM standard itself, prior to reading this conformance statement. Although the use of this conformance statement in conjunction with the DICOM 3.0 standard is intended to facilitate communication with Agfa IMPAX EE Mammography, it is not sufficient to guarantee, by itself, the inter-operation of the connection. The following issues need to be considered.

1.3

General Remarks

1.3.1

Integration and Validation Activities The integration of any device into a system of interconnected devices goes beyond the scope of the DICOM 3.0 standard and this conformance statement when interoperability is desired. The responsibility for analyzing the applications requirements and developing a solution that integrates the Agfa equipment with other vendors’ systems is the user’s responsibility and should not be underestimated. In some circumstances it might be necessary to perform a validation to make sure that functional interoperability between the Agfa equipment and non-Agfa devices works as expected. The user should ensure that any non-Agfa provider accepts responsibility for any validation required for their connection with the Agfa equipment.

1.3.2

Future Evolution As the DICOM 3.0 standard evolves to meet the user’s growing requirements and to incorporate new features and technologies, Agfa will follow the evolution of the standard. This evolution of the standard may require changes to devices that have implemented DICOM 3.0. The user should ensure that any non-Agfa provider, who connects with Agfa devices, also plans for future evolution of the DICOM standard. A refusal to do so may result in the loss of functionality and/or connectivity between the different products.

NETWORKING

2.1

Implementation Model All DICOM Services provided by IMPAX EE Mammography are implemented in one process, which is launched and terminated by the user. This process hosts a DICOM server listening on different ports that requires the assignation of an Application Entity Title to the application. That motivates to describe the DICOM functionality of IMPAX EE Mammography as provided an Application Entity: 

IMPAX EE Mammography CLIENT provides DICOM Services related with images and DICOM Structured Report Documents that includes Storage Services to receive images of MG, CR, US modalities, Grayscale Presentation States (GSPS), Key Object (KO) and Structure Report (SR) Documents. Selection Documents, but also the Storage Commitment Push Model Service as Service Class User (SCU), and Query/Retrieve Services, to query archives for available images, GSPS and KO objects and repositories for available SR documents. These Services also retrieve such DICOM information objects triggered by user interactions.

Verify the connection to DICOM peer Application Entities (AEs) by acting as DICOM Verification SCU and SCP Query and retrieve images, SR, GSPS and KO from DICOM peer AEs by acting as DICOM Query/Retrieve SCU. Receive images, GSPS, KO and SR from DICOM peer AEs by acting as SCP for various Image Storage SOP Classes, DICOM Grayscale Presentation State Storage SOP Class, and KO Selection Document Storage SOP Class. Request storage commitment of image, KO, SR and GSPS Information Entities (IEs) to DICOM peer AEs by acting as DICOM Storage Commitment Push Model SCU. Send query to a Modality Worklist by acting as SCU and then sends a Modality Performed Procedure Step (MPPS) message to a remote AE.

Sequencing of Real World Activities Any retrieval of images by the IMPAX EE Mammography AE from a peer AE has preceded by – one or several – query requests to the peer AE, to get information about available images and values of study/series/image identifiers necessary for creating retrieve requests. Typically the receipt of images by the IMPAX EE Mammography AE from a peer AE is caused by an Image Retrieve Request to this peer AE by the IMPAX EE Mammography AE. The IMPAX EE Mammography AE creates derived images from source images. Image IEs have to be received by the IMPAX EE Mammography AE, before they can be stored to or printed at peer AEs.

The maximum PDU length is 16384 bytes. SOP Class extended negotiation is supported.

2.2.1.2.2

Number of Associations Typically the IMPAX EE Mammography AE initiates only one DICOM Association concurrently, but potentiality the number of parallel associations is only limited by the resources of the underlying operating system. Several DICOM Associations will be initiated concurrently, if the user launches a new Query/Retrieve, before an already performing Query/Retrieve operation was finished. Several open DICOM Associations may also occur during Storage Commitment, if the Storage Commitment SCP peer AE sends the Commitment Result in a separate Association – initiated by the peer AE and accepted by the IMPAX EE Mammography AE.

2.2.1.3.2.4

SOP Specific Conformance Statement for Q/R Patient Root Information Model – FIND By default, IMPAX EE Mammography Application uses Query/Retrieve Study Root Info. Model – FIND. In case that server does not support this SOP Class, IMPAX EE Mammography uses Query/Retrieve Patient Root Info. Model – FIND. Queries initiated by the user without selection of any Patient/Study entry are performed with query level STUDY. When querying SR objects, queries are initiated by the user selection of the Study entry (as indicated in Table 2.2-6 are performed with query level SERIES) and matching key Modality (0008,0060) = SR. If the Query Response contains entries for matching Series, a Retrieve for the SR Objects of this Series will be initiated.

Description and Sequencing of Activity

The user of the IMPAX EE Mammography Application selects single images, series or complete studies and the destination AE in the local Patient/Study Folder before initiating the Image Storage by selecting the corresponding button on the user interface. Importing images, GSPS, KO and SR from external source or archive is the only possible way for storing such objects. At default, all Grayscale Presentation State Objects associated with selected images will be stored to the selected import destination. Also the selected Key Objects will be stored. The storage of images is reflected by a status change of the corresponding item in the Patient/Study Folder. If the destination AE also supports the Storage Commitment Push Model service - or a separate AE is associated with the destination AE to perform the Storage Commitment operation -, at default configuration, IMPAX EE Mammography sends a Storage Commitment request for the transmitted images and GSPS objects immediately after the storage operation was finished.

At default, IMPAX EE Mammography releases the association immediately after it receives the N-ACTION RSP to the initial Storage Commitment N-ACTION Request. That forces the peer AE, to send the N-EVENT-REPORT request containing the commitment result in a separate association, which has to be initiated – and released – by the peer AE. The default behavior can be changed, that IMPAX EE Mammography keeps the initial association open until the corresponding N-EVENT-REPORT request was received and immediately confirmed by IMPAX EE Mammography – no matter if in the same or in a separate association. If a complete success of the requested Storage Commitment is notified by the N-EVENTREPORT, the status of the concerned image and presentation state objects changes to “committed”, which enables the user to delete these objects. If existing failure of the requested Storage Commitment is notified by the N-EVENTREPORT, the user will be asked, if the status of image and presentation state objects for which a successful commitment was reported, shall be changed to “committed”.

Receive images, GSPS, KO and SR IMPAX EE Mammography CLIENT accepts an association when it receives an association request from a DICOM Storage SCU.

2.2.1.4.2.1

Description and Sequencing of Activity The receipt of an Image Storage Request is typically caused by a Retrieve Images Request issued by the IMPAX EE Mammography application entity to the remote system. When IMPAX EE Mammography accepts an association, it will receive any image, GSPS, KO or SR transmitted on that association and store the image locally and register it in the local database. The IMPAX EE Mammography application entity informs the user of the receipt of new objects.
