Abstract :
Mass Spring Model (MSM) is widely used in the simulation of soft tissue deformation due to its high efficiency. However, the anisotropic property of soft tissue challenges such a simulation. This manuscript proposed an improved MSM by taking into consideration of anisotropic property. Firstly, the anisotropic property of soft tissue is investigated. Then, the parameters of MSM are set according to the investigation. Finally, the force on each spring is combined by axial and radial forces. Experimental results illustrates the proposed method can simulate deformation accurately. It shows prospective in the application of surgical simulation.
