2P1-U03 Evaluation of Real-time Performance of the Blunt Dissection Simulator using a Real Brain Model(Surgical Robotics and Mechatronics(2))

Abstract

Surgery simulator is expected to help plan surgery procedures and train surgical techniques. In brain surgery, blunt dissection simulation is needed because it is a basic and important technique. Nakayama et al. proposed a method of computing fracture of soft tissue for blunt dissection simulation. However real-time simulation had not been achieved because of its high computational cost. This paper shows the system of the blunt dissection simulator with a haptic interface, and proposes a method for construction of real brain Finite Element Method(FEM) model by scanning the surface of a pig brain using a laser displacement sensor. Additionally the real-time performance of the simulator which parallelized by a multi-core processor is evaluated.
