Section 1 Scope and Field of Application

This part of the DICOM Standard is Part 5 (PS 3.5) of a multi-part standard produced to facilitate the interchange of information between digital imaging computer systems in medical environments. This interchange will enhance diagnostic imaging and potentially other clinical applications. The multi-part DICOM Standard covers the protocols and data that shall be supplied to achieve this interchange of information.

In this part of the standard the structure and encoding of the Data Set is specified. In the context of Application Entities communicating over a network (see PS 3.7), a Data Set is that portion of a DICOM Message that conveys information about real world objects being managed over the network. A Data Set may have other contexts in other applications of this standard; e.g., in media exchange the Data Set translates to file content structure.

This part of the DICOM Standard specifies:

a) the encoding of Values

b) the structure and usage of a Data Set

c) Data Element usage and relationships to other elements

d) the construction and usage of Nested Data Sets

e) the construction and usage of Data Sets containing Pixel Data

f) how to uniquely identify information

g) the specification of the standard DICOM Transfer Syntaxes

This part of the DICOM Standard does not specify:

a) the structure and syntax of a message (this is specified in PS 3.7)

b) the structure and usage of a command set (this is specified in PS 3.7)

c) how an application service functions or is classified (this is specified in PS 3.3 and PS 3.4)

d) how data sets relate to network communication, media storage, or other services
