A.5.3.10 Query

A.5.3.10 Query (Current)
Prev	A.5.3 DICOM Specific Audit Messages	Next

This message describes the event of a Query being issued or received. The message does not record the response to the query, but merely records the fact that a query was issued. For example, this would report queries using the DICOM SOP Classes:

Modality Worklist
UPS Pull
UPS Watch
Composite Instance Query

Note

The response to a query may result in one or more DICOM Instances Transferred or DICOM Instances Accessed messages, depending on what events transpire after the query. If there were security-related failures, such as access violations, when processing a query, those failures should show up in other audit messages, such as a Security Alert message.
Non-DICOM queries may also be captured by this message. The Participant Object ID Type Code, the Participant Object ID, and the Query fields may have values related to such non-DICOM queries.
