GEMS INFORMATION TECHNOLOGIESCENTRICITY PACS 1.0 CONFORMANCE STATEMENTREV 0, MAY 2002 IIS FP 106172. NETWORK CONFORMANCE STATEMENT2.1 INTRODUCTIONCentricity PACS provides (image and non-image) data management and archival services. Itimplements a DICOM Communication Server (denoted DICOM Server for short in this document) forthe following services to external systems (e.g., acquisition modalities, review workstations, etc.):xReceive DICOM Storage SOP Instances from an acquisition modality for data storage.xServe long-term storage commitment request for the SOP Instances. These SOP Instances can bealready sent to the PACS previously or delivered at a later time after the Storage Commitmentrequest.xSend DICOM Storage SOP Instances to an external system for data distribution.xServe information query and data retrieval to the Patient / Study / Series / SOP Instancesmaintained in the Centricity PACS system.The DICOM Server creates a number of DICOM Application Entities (AEs) to support these services.Each DICOM AE will be dedicated to a particular type of the DICOM services, as explained in the restof the document.Centricity PACS also supports the DICOM Print as SCU. The DICOM Print service has beenimplemented in a separate subsystem other than the DICOM Server. Section 7 includes a completeDICOM v3.0 Standards Conformance Statement for the Print service.Note:In this document, we use the term “DICOM Storage SOP Instance” or “SOP Instance” inplaces where the term “Image” is usually used. A SOP Instance generally refers to a DICOMv3.0 Standards Composite IOD, which can be an image or non-image data set. The SOP classto which an instance is associated determines the data type of the instance in the most cases.For detail, the reader is referred to DICOM PS 3.3 and 3.4, 1999.Centricity PACS supports a RIS interface to receive study orders as well as patient / study updates.Alternatively, the Centricity Exam Manager operator can also create a study order directly in thedatabase. Centricity PACS supports a DICOM Modality Worklist information query to the orderedstudies from an acquisition modality. The modality includes the patient / study information received inthe query responses to the DICOM Storage SOP instances it generates and sends these to the StorageAE of the DICOM Server.After receiving the DICOM SOP instances, the Storage AE will match the SOP instances to theassociated study in the Centricity database, using the patient / study information embedded in thedata sets of the instances. Using the worklist query is highly recommended for all acquisitionmodalities. If a modality cannot support the worklist query, it usually relies on the operator’s input forthe patient / study information. Without the use of a modality worklist, manual errors increase thenumber of mismatching SOP instances to the studies in the Centricity database significantly.2–7
