This value set expansion contains 2 concepts.

System	Version	Code	Display	Definition
`http://terminology.hl7.org/CodeSystem/v3-ActCode`	8.0.0	ROIFS	fully specified ROI	A fully specified bounded Region of Interest (ROI) delineates a ROI in which only those dimensions participate that are specified by boundary criteria, whereas all other dimensions are excluded. For example a ROI to mark an episode of "ST elevation" in a subset of the EKG leads V2, V3, and V4 would include 4 boundaries, one each for time, V2, V3, and V4.
`http://terminology.hl7.org/CodeSystem/v3-ActCode`	8.0.0	ROIPS	partially specified ROI	A partially specified bounded Region of Interest (ROI) specifies a ROI in which at least all values in the dimensions specified by the boundary criteria participate. For example, if an episode of ventricular fibrillations (VFib) is observed, it usually doesn't make sense to exclude any EKG leads from the observation and the partially specified ROI would contain only one boundary for time indicating the time interval where VFib was observed.
