Memory and apparatus pertaining to the automated calculation of supplemental patient volume information

摘要

A control circuit that operably couples to a memory having a radiation-treatment plan stored therein that is based upon a particular patient volume receives subsequent information regarding that particular patient volume and automatically uses that subsequent information to calculate supplemental patient volume information to be used by the radiation-treatment plan. By one approach this supplemental patient volume information comprises replacement information to be used in lieu of the presumed patient volume information. The foregoing may include applying at least one rule to effect the aforementioned calculation, applying one or more deformable registration algorithms, and/or one or more Boolean operators.
