COND: entryRelationship SHALL NOT be present in a 10.8 SOP Instance Observation included within a 9.8.7 DICOM Object Catalog section, and MAY be present otherwise.
This template recursively invokes itself to allow a Presentation State SOP Instance reference to identify the target Image SOP Instances, or for a derived Image to reference its source Image, or similar linkages between instances.
This is generally not required, as the DICOM SOP Instance itself identifies relationships to the relevant other SOP Instances.
A Purpose of Reference Observation describes the purpose of the DICOM composite object reference. Appropriate codes, such as externally defined DICOM codes, may be used to specify the semantics of the purpose of reference. When this observation is absent, it implies that the reason for the reference is unknown.
In Consolidated CDA r1.1, this was defined using a separate "Purpose of Reference Observation" template, which is included directly in this template specification.
A Referenced Frames Observation contains a list of integer values for the referenced frames of a DICOM multi-frame image SOP instance. It identifies the frame numbers within the referenced SOP instance to which the reference applies. The observation identifies frames using the same convention as DICOM, with the first frame in the referenced object being Frame 1. A Referenced Frames Observation must be used if a referenced DICOM SOP instance is a multi-frame image and the reference does not apply to all frames.
In Consolidated CDA r1.1, this was defined using separate "Referenced Frames Observation" and "Boundary Observation" templates, which are included directly in this template specification.
