Real-time Dynamic Bleeding Synthesis and Simulation of Endoscopic Images

A real-time dynamic bleeding synthesis and simulation model based on computational fluid dynamics is proposed,which aims at realistic simulation of bleeding in the endoscopic surgical training systems based on virtual reality.Navier-Stokes equations are adopted to simulate blood flow as an incompressible fluid.A faster solution to Navier-Stokes equations is employed to solve the density field and velocity field in order to develop a real-time system.In light of this solution,a prototype of bleeding model with OpenGL was implemented.The results show that this method applied to the bleeding simulation is elucidating and practical.
