Abstract

Bone dissection is an important component of many surgical procedures. In this paper, we discuss a haptic and visual implementation of a bone-cutting burr that is being developed as a component of a training system for temporal bone surgery. We use a physically motivated model to describe the burr-bone interaction, which includes haptic force evaluation, the bone erosion process and the resulting debris. The current implementation, directly operating on a voxel discretization of patient-specific 3D CT and MRI data, is efficient enough to provide real-time feedback on a low-end multiprocessing PC platform
