Abstract
The current major difficulties are to establish accurate models to perform real-time simulation of soft tissue deformation for virtual palpation system, which is the contradiction between accuracy and real-time. This paper proposes a method that uses the parameters of the finite element method to estimate the elastic coefficient of mass-spring model and introduces the damping coefficient to rewrite the Euler integral, then builds a virtual palpation system for simulation. The experimental results show that the method is accurate while the real-time performance is guaranteed.
