Bone dissection is an important component of many surgical procedures. We discuss a haptic implementation of a bone cutting burr, that it 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 process. The model includes haptic forces evaluation, the bone erosion process and the resulting debris. The current implementation, directly operating on a voxel discretization of patient-specific 3D imaging data, is efficient enough to provide real-time feedback on a low end multi processing PC platform. This research is supported by the IERAPSI project (EU-IST-1999-12175), funded under the European IST programme (Information Society Technologies).
