Real Time Volumetric Deformable Models for Surgery Simulation

Surgical simulation increasingly appears to be a mandatory aspect of tomorrow s surgery From today s gesture training surgical simulators will evolve in order to perform surgical planning with the ability to rehearse the various steps of the operation thus reducing oper ating time and risks In this paper we describe a virtual environment for surgical training and more speci cally a model based on elasticity theory which conveniently links the shape of deformable bodies and the forces associated with the deformation while achieving real time performance
