Abstract

Systems, computer-implemented methods, and computer program products are provided for automated planning of a cutting boundary for removal of a diseased region of an anatomy, such as a bone tumor. A model is provided for the diseased region of the anatomy, and optionally, a healthy region of the anatomy. One or more cutting geometries are defined relative the diseased region. Algorithms are provided which enable automated optimization of characteristics (e.g., shape, size, position, orientation) of the cutting geometries relative to the diseased region in order to plan for complete removal of the diseased region, en bloc, while minimizing an amount of healthy region to be removed.
