TID 4125 Colon CAD Composite Feature Template

This template collects a composite feature for a lesion, non-lesion object, or correlation of related objects (see TID 4121). The details of the composition are expressed in the Colon CAD Composite Feature Body (see TID 4126). The data from which the details are inferred, are expressed in the Composite Features (see TID 4125) and/or Single Image Findings (see TID 4127), of which there may be several.

TID 4125COLON CAD COMPOSITE FEATURE

Type: Non-Extensible Order: Significant

NL Rel with Parent VT Concept Name VM Req Type Condition Value Set Constraint
1 CODE EV (111015, DCM, “Composite Feature”) 1 M DCID (6201) Colon Finding or Feature
2 > HAS CONCEPT MOD CODE EV (112023, DCM, “Composite Feature Modifier”) 1 U DCID (6202) Colon Finding or Feature Modifier
3 > HAS CONCEPT MOD CODE EV (111056, DCM, “Rendering Intent”) 1 M DCID (6034) Intended Use of CAD Output
4 >> HAS PROPERTIES NUM EV (111071, DCM, “CAD Operating Point”) 1 UC IFF value of row 3 is (111151, DCM, “Presentation Optional”) and row 1 of TID 4023 is present for the feature identified in row 1. UNITS = DT ({1:n}, UCUM, “range: 1:n”), where n is the maximum specified in Row 1 of TID 4023 for the feature identified in row 1. Value is restricted to being an integer.

Content Item Descriptions

Rendering Intent This content item constrains the SCP receiving the Colon CAD SR IOD in its use of the contents of this template and its target content items. Colon CAD devices may opt to use data marked “Not for Presentation” or “Presentation Optional” as input to subsequent colon CAD processing steps. Refer to PS 3.4, Annex O Structured Reporting Standard SOP Classes for SCU and SCP Behavior.
