Conformance Statement Overview
"Workstation", implements the necessary DICOM services to facilitate receiving of unprocessed CR images
from an AGFA Digitizer, performing image processing and sending the processed images to a remote
storage or print device over a Medical Imaging Systems network. "Workstation" may also acquire patient
information from a Radiology Information System (RIS) for use in identifying processed images.

1.2 Purpose and Intended Audience of this Document
This document is a DICOM Conformance Statement for the DICOM Services of the "Workstation" product. It
is written according to part PS 3.2 of Digital Imaging and Communications in Medicine (DICOM) 3.0, NEMA
PS 3.1-3.16, 2004.
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 ADC imaging equipment, it is not sufficient to guarantee, by itself, the
inter-operation of the connection.
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.

2.1.2 Functional Definitions of AE’s
2.1.2.1 Functional Definition of DICOM Store Application Entity
The DICOM Store Application Entity sends images and Presentation States to a remote AE (This can be a
configured Archiving station, a diagnostic workstation …). It is associated with the local real-world activity
“Send Images & GSPS”. If Storage Commitment is configured for the archive destination, the DICOM Store
AE will request Storage Commitment and a job will only be marked as successful when the commitment is

successfully obtained. An image that has been successfully sent to an archive cannot be sent to that archive
again.
2.1.2.2 Functional Definition of DICOM Print Application Entity
The DICOM Print Application Entity prints images on a remote AE (A configured Printer). It is associated with
the local real-world activity “Request to print film sheets”. A job will only be marked as “successful” when the
sheet is successfully printed.
2.1.2.3 Functional Definition of RIS Application Entity
The RIS Application Entity receives Worklist information from a remote AE. It is associated with the local
real-world activity “Query RIS”. This can be triggered manually by clicking the “Query RIS” button or triggered
automatically at a specified interval. When properly configured, the RIS can also be queried by Accession
Number.
The RIS query can be configured in different ways (for the possible configurations, see § 2.4.1.2.2.1). The
two that are relevant for DICOM are described in the following paragraphs:
2.1.2.3.1 DICOM Modality Worklist
The use of DICOM Modality Worklist (DMWL) queries the RIS by means of query keys. The query keys can
be changed by the user in the configuration tool (see § 2.4.1.2.2.1). Based on these keys, the worklist will be
populated during the next RIS query.
2.1.2.3.2 DICOM Modality Worklist query on Accession Number
By querying by Accession Number, only the worklist items that contain the specified Accession Number are
returned. These results are parsed, mapped and shown as a Worklist.
2.1.2.4 Functional Definition of MPPS Application Entity
The MPPS Application Entity sends MPPS information to a remote AE when MPPS reporting is configured.
The local real-world activities “Acquire Images”, “Archive Images” and “Print Images” can trigger the creation
of an MPPS instance. This can also be done by adding a new SOP Instance UID to a MPPS, by adding a
Dose to a MPPS or by adding a Print Sheet to a MPPS. The local real-world activity “Close Session” or the
modification of the session’s Accession Number will complete the MPPS. This happens completely
automatically and no user intervention is possible.
