10.2 Content Item Macro

A Content Item is a flexible means of encoding attribute identifiers and attribute values using the Code Sequence Macro (see Section 8) for coded terminology defined by a coding scheme. The Content Item provides a name-value pair, i.e., a Concept Name, encoded as a Code Sequence, and a Concept Value. The Concept Value may be encoded by any of a set of generic Attributes, as specified by a Value Type, including text, personal name, numeric, and coded concept (Code Sequence) values.

Note

  1. Comparing a Content Item to a native DICOM Data Element, the Concept Name Code Sequence corresponds to the Data Element Tag and Attribute Name, the Value Type to the Value Representation, and the Concept Value to the Data Element Value Field. See PS3.5.

  2. The IMAGE Value Type of this Macro does not include the Type 3 Attributes of the IMAGE Value Type defined in Section C.17.3, as they are not required for Acquisition Context or Protocol Context Content Items.

Specific uses of the Content Item may invoke the Content Item Macro defined in this Section, the Document Content Macro of Section C.17.3, or another similar construct. An invocation of the Content Item Macro may constrain the allowed values of Value Type (0040,A040).

Note

  1. The NUMERIC Value Type of this Macro differs from the NUM Value Type defined in Section C.17.3, since the encoding of the Concept Value is different.

  2. The Value Type uses Enumerated Values so as to assure that non-standard Value Types are not used, and to prevent the nefarious use, for example, of a CONTAINER Value Type in an SR-like manner to create nested content, which is not the intent.

  3. Some invocations of this Macro may use the Content Item Modifier Sequence (0040,0441) to achieve a single level of "nesting". That Attribute is not included in this Macro itself, to prevent recursive inclusion.

See Section 5.4 for the meaning of the Type column in this Macro when applied to Normalized IODs.

10.2.1 Content Item With Modifiers Macro

Content Item with Modifiers is a means of describing structured content which needs a Content Item with single optional level of modifiers, i.e. a two-level structure of Content Items. An invocation of the Content Item with Modifiers Macro will usually specify the allowed values using a Protocol Context Template in PS3.16, which allows a single Nesting Level (see in Section 6.1.2 “Nesting Level (NL)” in PS3.16 ). Constraints on the use of this Macro may be specified in PS3.16 Annex C, which may be invoked in IODs in PS3.3.
