Coupled tissue bleeding simulation in virtual surgery

Abstract

Tissue bleeding simulation is the key problem in virtual surgery, which greatly reduces the risk of real surgery. It also plays an important role in the application of fluid-solid coupling. Traditional methods of fluid-solid coupling are almost mesh-based, in this paper we proposed a tissue bleeding model as well as an improved collision detection and response algorithm based on SPH (Smoothed Particle Hydrodynamics). Our tissue bleeding model describes Navier-Stokes equations with SPH method and our tissue model is set as rigid body. Experimental results show that our coupled tissue bleeding simulation model possesses high fidelity and strong robustness. © 2013 Springer-Verlag.
