Abstract
Abstract—We present techniques for the visual and haptic simulation of bone surgery, with a specific focus on procedures involving the temporal bone and the mandible. We discuss our approaches to graphic and haptic rendering and interactive modification of volumetric data, specifically focusing on generating force-feedback effects that are relevant to bone drilling. We then discuss how our rendering primitives and simulation architecture can be used to build surgical training techniques that are not available in traditional cadaver-based training labs, offering new possibilities for surgical education. In particular, we discuss the automatic computation of performance metrics that can provide real-time feedback about a trainee’s performance in our simulator. We also present results from an experimental study evaluating the construct validity of our simulation and the validity of our performance metrics
