2A1-L02 Collision Detection for Real Time Surgery Simulation of Opening a Brain Fissure(Surgical Robotics and Mechatronics (1))

Abstract

In Neurosurgery, Opening a brain fissure allows an operator to access to basis cranii and to treat a disease part safely, but the operator is required high technique. The goal of this study is to develop a Neurosurgery simulator enabling surgeons to train opening a brain fissure procedure. Simulation of excluding soft tissue needs collision detection between a soft tissue and tools and choosing suitable contact displacement. In this study, collision detection considered its previous condition is proposed and opening a brain fissure simlation is performed with this method. In addition, the computation of collision detection is accelerated with GPU.
