DICOM PS3.4 2022c - Service Class Specifications

JJ Inventory Query/Retrieve Service Class

JJ.1 Overview

JJ.1.1 Scope

The Inventory Query/Retrieve Service Class defines an application-level class-of-service that facilitates discovery of and access to Inventory composite objects.

JJ.1.2 Conventions

See Conventions for the Basic Worklist Management Service (see Section P.1.2).

JJ.1.3 Service Definition

The SOP Classes of the Inventory Query/Retrieve Service Class are each composed of an Information Model and a DIMSE-C Service Group.

In order to serve as an SCP of the Inventory Query/Retrieve Service Class, a DICOM AE possesses information about the Attributes of a number of Inventory composite SOP Instances. The information is organized into an Inventory Query/Retrieve Information Model.

Two peer DICOM AEs implement a SOP Class of the Inventory Query/Retrieve Service Class with one serving in the SCU role and one serving in the SCP role. SOP Classes of the Inventory Query/Retrieve Service Class are implemented using the DIMSE-C C-FIND, C-MOVE and C-GET services as defined in PS3.7.

The semantics of the C-FIND service are the same as those defined in the Service Definition of the Basic Worklist Management Service Class (see Section C.1.4).

The semantics of the C-MOVE and C-GET services are the same as those defined in the Service Definition of the Query/Retrieve Service Class (see Section C.1.4), with the exception that there is only one level of retrieval.
