    Bone dissection is an important component of many surgical procedures. In this video, we demonstrate a haptic and visual 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, that 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 CT and MR imaging data, is efficient enough to provide real-time feedback on a low-end multi-processing PC platform. These results were obtained within the framework of the European Union IERAPSI project (EU-IST-1999-12175).
