# 1 Scope and Field of Application

This Part of the DICOM Standard specifies the DICOM Message Service Element (DIMSE). The DIMSE defines an Application Service Element (both the service and protocol) used by peer DICOM Application Entities for the purpose of exchanging medical images and related information.

The DIMSE provides its services by relying on the DIMSE protocol. The DIMSE protocol defines the encoding rules necessary to construct Messages. A Message is composed of a Command Set (defined in this part of the DICOM Standard) followed by a conditional Data Set (defined in PS3.5).

This Part specifies:

- a set of service primitives provided by the DIMSE Application Service Element

- the parameters that are passed in each service primitive

- any necessary information for the semantic description of each service primitive

- the procedures applicable to the service primitives

- the Abstract Syntax of the DICOM composite and normalized command protocol and the associated encoding rules to be applied

- procedures for the correct interpretation of protocol control information

- the conformance requirements to be met by implementation of this part of the Standard

- the Application Context required for DICOM Application Entities

- the Association requirements of DICOM Application Entities

- the Application Association Information for DICOM Application Entities

This Part is related to other parts of the DICOM Standard in that:

- PS3.3, Information Object Definitions, specifies the set of Information Object Definitions to which the services defined in this part may be applied

- PS3.5, Data Structure and Encoding, addresses the encoding rules necessary to construct a conditional Data Set that is conveyed in a Message as specified in this part

- This Part defines the protocols and services required to accomplish the Service Classes described in PS3.4
