A.88 Inventory IOD

A.88.1 Inventory IOD Description

The Inventory IOD defines an Inventory of all Studies, Series, and SOP Instances managed by a repository, or a specified subset of those Studies, Series, and SOP Instances. It includes information about the available mechanisms to access such Studies, Series, and SOP Instances, including both DICOM and non-DICOM protocols. The Inventory provides selected Patient, Procedure, and Imaging Service Request Attribute values for the inventoried Studies.

For implementation-specific reasons, a complete Inventory may need to be divided across multiple SOP Instances. The Inventory IOD allows a SOP Instance to reference other SOP Instances whose content is logically included by such reference. A complete inventory thus consists of one root SOP Instance, with a tree of references to additional SOP Instances, the content of all of which comprises the Inventory.


See additional explanatory information in Annex YYYY “Inventories (Informative)” in PS3.17, including discussion of the use of the Repository Query SOP Class or the Inventory Creation SOP Class to produce an Inventory SOP Instance.
