A.35.1 Basic Text SR Information Object Definition

A.35.1.1 Basic Text SR Information Object Description

The Basic Text Structured Report (SR) IOD is intended for the representation of reports with minimal usage of coded entries (typically used in Document Title and headings) and a hierarchical tree of headings under which may appear text and subheadings. Reference to SOP Instances (e.g. images or waveforms or other SR Documents) is restricted to appear at the level of the leaves of this primarily textual tree. This structure simplifies the encoding of conventional textual reports as SR Documents, as well as their rendering.

A.35.1.2 Basic Text SR IOD Entity-Relationship Model

The E-R Model in Section A.1.2 of this Part applies to the Basic Text SR IOD. The Frame of Reference IE, and the IEs at the level of the Image IE in Section A.1.2 are not components of the Basic Text SR IOD. Table A.35.1-1 specifies the Modules of the Basic Text SR IOD.

A.35.1.3 Basic Text SR IOD Module Table

Table A.35.1-1 specifies the Modules of the Basic Text SR IOD.

Note: The Specimen Identification Module was previously included in this IOD but has been retired. See PS 3.3-2008.

A.35.1.3.1 Basic Text SR IOD Content Constraints

A.35.1.3.1.1 Value Type

Value Type (0040,A040) in the Content Sequence (0040,A730) of the SR Document Content Module is constrained to the following Enumerated Values (see Table C.17.3-7 for Value Type definitions):

TEXT

CODE

DATETIME

DATE

TIME

UIDREF

PNAME COMPOSITE IMAGE WAVEFORM CONTAINER

A.35.1.3.1.2 Relationship Constraints

Relationships between Content Items in the content of this IOD shall be conveyed in the by-value mode. See Table C.17.3-8 for Relationship Type definitions.

Note: Relationships by-reference are forbidden. Therefore, Referenced Content Item Identifier (0040,DB73) is not present in any of the Content Items within the SR Document Content Module.

Table A.35.1-2 specifies the relationship constraints of this IOD.

Table A.35.1-2RELATIONSHIP CONTENT CONSTRAINTS FOR BASIC TEXT SR IOD

Source Value Type Relationship Type (Enumerated Values) Target Value Type
CONTAINER CONTAINS TEXT, CODE, DATETIME, DATE, TIME, UIDREF, PNAME, COMPOSITE1, IMAGE1, WAVEFORM1, CONTAINER
CONTAINER HAS OBS CONTEXT TEXT, CODE, DATETIME, DATE, TIME, UIDREF, PNAME, COMPOSITE1
CONTAINER, IMAGE1, WAVEFORM1, COMPOSITE1 HAS ACQ CONTEXT TEXT, CODE, DATETIME, DATE, TIME, UIDREF, PNAME
any type HAS CONCEPT MOD TEXT, CODE2
TEXT HAS PROPERTIES TEXT, CODE, DATETIME, DATE, TIME, UIDREF, PNAME, IMAGE1, WAVEFORM1, COMPOSITE1
PNAME HAS PROPERTIES TEXT, CODE, DATETIME, DATE, TIME, UIDREF, PNAME
TEXT INFERRED FROM TEXT, CODE, DATETIME, DATE, TIME, UIDREF, PNAME, IMAGE1, WAVEFORM1, COMPOSITE1

Note: 1. Which SOP Classes the IMAGE, WAVEFORM or COMPOSITE Value Type may refer to, is documented in the Conformance Statement for an application (see PS 3.2 and PS 3.4).

2. The HAS CONCEPT MOD relationship is used to modify the meaning of the Concept Name of a Source Content Item, for example to provide a more descriptive explanation, a different language translation, or to define a post-coordinated concept.
