RRR Measurement Report SR Document for Planar and Volumetric ROI (Informative)

This Annex contains examples of the use of ROI templates within Measurement Report SR Documents.

RRR.1 Measurement Report SR Document Volumetric ROI on CT Example

This CT example describes the minimum content necessary to encode a single measurement (volume) made from a single volumetric ROI encoded as a single segment that spans two source CT images.

Note

  1. References to Segmentation Image or Surface Segmentation objects are encoded as IMAGE references, with a single value specified in Referenced Segment Number.

  2. The method of volume calculation is not described in this example.
