### Note

The Specimen Identification Module was previously included in this IOD but has been retired. See PS3.3-2008.

##### A.35.6.3.1 Chest CAD SR IOD Content Constraints

###### A.35.6.3.1.1 Template Constraints

- The document shall be constructed from TID 4100 “Chest CAD Document Root” invoked at the root node.

- When a Content Item sub-tree from a prior document is duplicated by-value, its observation context shall be defined by TID 1001 “Observation Context” and its subordinate templates.

### Note

All Template and Context Group definitions are located in Annex A “Structured Reporting Templates (Normative)” in PS3.16 and Annex B “DCMR Context Groups (Normative)” in PS3.16, respectively.

###### A.35.6.3.1.2 Value Type

Value Type (0040,A040) in 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):

Enumerated Values:

TEXT

CODE

NUM

DATE

TIME

UIDREF

PNAME

SCOORD

TCOORD

COMPOSITE

IMAGE

WAVEFORM

CONTAINER

###### A.35.6.3.1.3 Relationship Constraints

The Chest CAD SR IOD makes use of by-reference INFERRED FROM, by-reference SELECTED FROM, and by-reference HAS PROPERTIES relationships. Other relationships by-reference are forbidden. Table A.35.6-2 specifies the relationship constraints of this IOD. See Table C.17.3-8 for Relationship Type definitions.

Table A.35.6-2. Relationship Content Constraints for Chest CAD SR IOD

Source Value Type | Relationship Type (Enumerated Values) | Target Value Type
--- | --- | ---
CONTAINER | CONTAINS | CODE, NUM, IMAGE1, CONTAINER
TEXT, CODE, NUM, CONTAINER | HAS OBS CONTEXT | TEXT, CODE, NUM, DATE, TIME, PNAME, UIDREF, COMPOSITE1.
IMAGE, WAVEFORM | HAS ACQ CONTEXT | TEXT, CODE, DATE, TIME, NUM.
CONTAINER, CODE, COMPOSITE, NUM | HAS CONCEPT MOD | TEXT, CODE2.
TEXT, CODE, NUM | HAS PROPERTIES | CONTAINER, TEXT, CODE, NUM, DATE, IMAGE1, WAVEFORM1, SCOORD, TCOORD, UIDREF.
CODE, NUM | INFERRED FROM | CODE, NUM, IMAGE1, WAVEFORM1, SCOORD, TCOORD, CONTAINER, TEXT.
SCOORD | SELECTED FROM | IMAGE1.
TCOORD | SELECTED FROM | SCOORD, IMAGE1, WAVEFORM1.

### Note

1. Which SOP Classes the IMAGE or COMPOSITE Value Type may refer to, is documented in the Conformance Statement for an application (see PS3.2 and PS3.4).

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.
