Abstract
In Computer Assisted Surgery (CAS), there is an increasing need for the data exchange between the planning system and external Computer Aided Design (CAD)/Computer Aided Manufacture (CAM) process to simulate the intraoperative execution or to verify and optimize the implant design. An interface for such data exchange was therefore implemented and integrated in the CAS system developed in our group. We also propose a simple, robust and fast algorithm for the voxelization of surface models with triangle meshes. The tools have been used successfully for the integration of standard geometry implant data for total knee arthroplasty. A surgical simulation and planning module for the robot assisted craniectomy will also use this interface to simulate intraoperative robotic milling and support the iterative design of the individual implant.
