# 3 Definitions

For the purposes of this Standard the following definitions apply.

## 3.1 Codes and Controlled Terminology Definitions:

The following definitions are commonly used in this Part of the DICOM Standard:

Baseline Context Group Identifier (BCID)

  Identifier that specifies the suggested Context Group for a Code Sequence Attribute.

  See Table 5.6-1 “Conventions for Specification of Context Groups” in PS3.3 .

Defined Context Group Identifier (DCID)

  Identifier that specifies the Context Group for a Code Sequence Attribute that shall be used.

  See Table 5.6-1 “Conventions for Specification of Context Groups” in PS3.3 .

Extensible Context Group

  Context Group that may be extended by a particular application by inclusion of additional concepts.

  See Table 5.6-1 “Conventions for Specification of Context Groups” in PS3.3 .

Non-Extensible Context Group

  Context Group whose defined set of concepts shall not be extended by an application.

  See Table 5.6-1 “Conventions for Specification of Context Groups” in PS3.3 .

Context Group

  A set of coded concepts defined by a Mapping Resource forming a set appropriate to use in a particular context.

Context Group Version

  Version of a Context Group.

Context ID (CID)

  Identifier of a Context Group.

Mapping Resource

  A resource that defines context-dependent usage constraints (i.e., Value Set or Relationship Type restrictions) for Attributes. A resource that specifies the mapping of the content of an external controlled terminology to the components of a message standard.

Relationship Type

  The association between two Concepts. Examples: "HAS PROPERTIES", "CONTAINS", "INFERRED FROM".

DICOM Content Mapping Resource (DCMR)

  A Mapping Resource that defines Templates and Context Groups for use in DICOM IODs.

Template

  A pattern that describes the Content Items, Value Types, Relationship Types and Value Sets that may be used in part of a Structured Report content tree, or in other Content Item constructs, such as Acquisition Context or Protocol Context. Analogous to a Module of an Information Object Definition.

Template ID (TID)

  Identifier of a Template.

Value Set

  The allowed values of a Code Sequence Attribute in a given context. Specified either as one or more individual values or by reference to a Context Group.

Baseline Template Identifier (BTID)

  Identifier that specifies a Template suggested to be used in the creation of a set of Content Items.

Defined Template Identifier (DTID)

  Identifier that specifies a Template that shall be used in the creation of a set of Content Items.

Extensible Template

  A Template that may be extended by a particular application by inclusion of additional Content Items beyond those specified in the Template.

Non-Extensible Template

  A Template that specifies the exact set of Content Items and corresponding Value Sets that shall be used and that shall not be extended by an application.

Root Template

  A Template whose first content item is a CONTAINER content item intended to be encoded in the top level Data Set of a SOP Instance. I.e., the "root node" of the "content tree".

Coding schemes

  Dictionaries (lexicons) of concepts (terms) with assigned codes and well defined meanings.

  ### Note

  Examples of coding schemes include SNOMED and LOINC.

## 3.2 Information Object Definitions:

This Part of the Standard makes use of the following terms defined in PS3.3:

Code Sequence Attribute

  See PS3.3.
