Any Content Item in the Content Tree that has been inserted (i.e., duplicated) from another SR object instance has a HAS OBS CONTEXT relationship to one or more Content Items that describe the context of the SR object instance from which it originated. This mechanism may be used to combine reports (e.g., Colon CAD SR 1, Colon CAD SR 2, Human).
The CAD Processing and Findings Summary section of the SR Document Content Tree of a Colon CAD SR IOD may contain a mixture of current and prior single image findings and composite features. The Content Items from current and prior contexts are target Content Items that have a by-value INFERRED FROM relationship to a Composite Feature Content Item. Content Items that come from a context other than the Initial Observation Context have a HAS OBS CONTEXT relationship to target Content Items that describe the context of the source document.
In Figure SS.2-1, Composite Feature and Single Image Finding are current, and Single Image Finding (from Prior) is duplicated from a prior document.
