Development of an elastic organ model containing voxel information

We have been developing a virtual surgery system that can simulate various surgical maneuvers on elastic organs with haptic feedback, and we have constructed an elastic organ model called the sphere-filled model. This paper describes a method for making a deeper incision in the same region and a slanting incision that approaches the resection for volume data by the use of the sphere-filled model. Using this method, we are able to perform not only pushing and pinching but various incisions that approach the resection in this system.
