      <p>A derivative of the RIM Observation class that represents a region of interest on an image, using an overlay shape. RegionOfInterest is used to make reference to specific regions in images, e.g., to specify the site of a physical finding by &quot;circling&quot; a region in a schematic picture of a human body. The units of the coordinate values in RegionOfInterest.value are in pixels, expressed as a list of integers. The origin is in the upper left hand corner, with positive X values going to the right and positive Y values going down. The relationship between a RegionOfInterest and its referenced ObservationMedia or ExternalObservation is specified by traversing the entryRelationship or reference class, respectively, where typeCode equals &quot;SUBJ&quot;. A RegionOfInterest must reference exactly one ObservationMedia or one ExternalObservation. If the RegionOfInterest is the target of a &lt;renderMultimedia&gt; reference, then it shall only reference an ObservationMedia and not an ExternalObservation.</p>
      <p>An XML attribute &quot;ID&quot; of type XML ID, is added to RegionOfInterest within the CDA Schema. This attribute serves as the target of a renderMultiMedia reference (see renderMultiMedia). All values of attributes of type XML ID must be unique within the document (per the W3C XML specification).</p>
