# 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.
