Abstract

Extensions to our collocated virtual reality and haptic techniques for simulation of a common form of brain surgery, ventriculostomy, will be explored to research a new simulator for a common step of spinal surgery, pedicle screw placement. We will help “improve health” by evaluating the spine surgery simulator for its realism and its effectiveness in teaching. Within the context of our simulator, the research involves exploring new surface deformation model for the deformability of skin over the spine and apply it to the insertion of pedicle screws through the skin in minimally invasive surgery, volumetric modeling to investigate accurate conversion of MRI data into 3D anatomical models, and simulation of real-time volume removal of bone during cutting or drilling operations.
