7.14.3 Conceptual Volume

The Conceptual Volume is a reference to a certain anatomical region or point. Conceptual Volumes may or may not have a representation in segmented images. In most cases they will be related to one or more volumetric representations in various image sets taken at different times.

For example, during a radiotherapy course at the time of prescription, physicians specify regions to which dose is prescribed. Subsequently these regions are referenced in other objects in order to track calculated and delivered dose in the course of treatment. This referencing capability is provided by the Conceptual Volume.
