6.7 PS 3.7: Message Exchange

PS 3.7 of the DICOM Standard specifies both the service and protocol used by an application in a medical imaging environment to exchange Messages over the communications support services defined in PS 3.8. A Message is composed of a Command Stream defined in PS 3.7 followed by an optional Data Stream as defined in PS 3.5.

PS 3.7 specifies:

— the operations and notifications (DIMSE Services) made available to Service Classes defined in PS 3.4,

— rules to establish and terminate associations provided by the communications support specified in PS 3.8, and the impact on outstanding transactions

— rules that govern the exchange of Command requests and responses

— encoding rules necessary to construct Command Streams and Messages.
