Abstract

Abstract: Although recent years have witnessed great improvement in the research of biomechanical simulation with user interactions for surgical simulation, it still suffers from many challenges such as computational model of soft tissue undergoing large deformation, collision detection, volume conservation, etc. A simple and efficient framework was proposed to meet these challenges. To well reproduce the mechanical response of organs, point based method was used to model the elastic solids undergoing large deformations. In addition, position based dynamics was adopted to model the objects collision, friction and volume conservation, which considerably improved the real-time performance and stability of complex interactions in surgical simulation. The method was validated in several benchmark problems. Experiments results demonstrate the effectiveness of the framework in terms of both visual effects and stability. In addition, the computational model for deformation has a great potential to be extended to interactive biopsy and cutting simulation.
