Abstract

A system according to invention principles automatically calculates anatomical feature (e.g., tumor, body part, organ) size electronically to provide a clinician with useful information when assessing the tumor response during treatment. A system for monitoring change in patient anatomical features, includes a volumetric analyzer for automatically analyzing data derived from an imaging unit that represents a three dimensional view of a patient anatomical feature in order to determine spatial characteristics of the anatomical feature. A comparison processor automatically compares a first set of spatial characteristics of a patient anatomical feature derived at a first time with a second set of corresponding spatial characteristics of the patient anatomical feature derived at a subsequent second time, to provide change data representing change in spatial characteristics of the patient anatomical feature over a period of time. A repository stores change data for access by a user.
