摘要：

In this paper, the simulation of soft tissue deformation in virtual surgery is studied. Because linear elastic model and explicit Euler integration are implemented in most of mass spring model, its realism and real-time is too low. To overcome these disadvantages, an improved mass spring model and its simulation algorithm for soft tissue deformation are proposed. Tetrahedral mass spring model is constructed firstly, in which an improved mechanical model is defined to reduce the probability of super elasticity and improve the realism of simulation. Then, a dynamic local simulation solution algorithm is presented to solve the deformation equations, based on an improved explicit Euler integration. Experiment results show that these proposed methods have better realism, real-time and stability than the traditional methods, so they can be implemented to real time simulation of soft tissue deformation. © 2013 Binary Information Press.
