Abstract
We describe a neurosurgical planning support system that we developed on a workstation. It enables a surgeon to generate useful 3-D images interactively and to simulate surgery on the computed images pre-surgically to confirm the optimum parameters for the instruments used in stereotactic surgery. In particular, we introduce two techniques for implementing indispensable functions in systems like this. One is an algorithm that can detect boundaries in medical images, and the other is an algorithm that can reduce the volume of polygonal data for surface-rendered images. These techniques move our system a step toward clinical use.
