  121080	Best illustration of finding	A selection of composite instances that best illustrates a particular finding.
  121112	Source of Measurement	Image or waveform used as source for measurement.
  121200	Illustration of ROI	Illustration of a region of interest.
  121191	Referenced Segment	Segment selected as a subset of a segmentation image, specifically the pixels/voxels identified as belonging to the classification of the identified segment.
  121214	Referenced Segmentation Frame	Frame selected from a segmentation image, specifically the pixels/voxels identified as belonging to the classification of the segment encompassing the identified frame.
  121231	Volume Surface	Surface of an identified or measured volume.
  121232	Source series for segmentation	Series of image instances used as source data for a segmentation.
  121233	Source image for segmentation	Image instances used as source data for a segmentation.
  125201	Illustration of Finding	An image that is a pictorial representation of findings. The concept is typically used as a purpose of reference to an image, such as a depiction of myocardium segments depicting wall motion function.
  126100	Real World Value Map used for measurement	A reference to the Real World Value Map applied to the stored image pixel values before their use for a measurement
  130401	Visual explanation	A visual explanation of how an algorithm produced its results.
  130488	Region in Space	A continuous part of space, not necessarily associated with a particular image.
  130489	Referenced Region of Interest Identifier	A reference to an identifier of a Region of Interest.For example, the value of ROI Number (3006,0022) within an Item of Structure Set ROI Sequence (3006,0020) in an Instance of RT Structure Set Storage SOP Class.
  128180	For RT Workflow	Instances available as input for a general radiotherapeutic workflow.
  128181	Diagnostic Source Images	Instances used to make a diagnosis.
  128182	Segmentation Result	Instances created during a segmentation session.
  128183	Registration Result	Instances created during a spatial registration.
  128184	Pre-Planning Result	Instances created during preparation prior to planning.
  128185	RT Prescription Result	Instances created for prescription of a radiotherapeutic treatment.
  128186	Dose Calculation Image Series	Image instances that represent an image series that is intended to be the primary input for the dose calculation. Any parameters required for dose calculation (such as electron density) is derived from this series.
  128187	Coordinate Alignment Image Series	Image instances that represent an image series from which the display coordinate system for a radiotherapeutic treatment planning is derived. Typically this series does not provide the parameters required for the dose calculation.
  128188	RT Treatment Simulation Result	Instances created during the simulation of a radiotherapeutic treatment delivery session. May also include input objects actually used.
  128189	RT Planning Result	Instances created during the planning of a radiotherapeutic treatment. May also include input objects actually used.
  128190	Dosimetric Result	Instances created during the creation of the dosimetric result of a radiotherapeutic treatment plan. May also include input objects actually used.
  128191	Patient Setup Verification Result	Instances created during the verification of the patient’s treatment position. May also include input objects actually used.
  128192	RT Treatment Session Result	Instances created during the treatment session. May also include input objects actually used.
  128193	RT Treatment Course Summary	Instances created during a treatment course. May also include input objects actually used.
  128194	RT Treatment QA Result	Instances created during evaluation of the treatment delivery quality. May also include input objects actually used.
  128195	For Diagnosis	Instances available to make a diagnosis.
  128196	For Segmentation	Instances available for segmentation.
  128197	For RT Prescription	Instances available for prescribing a radiotherapeutic treatment delivery.
