Abstract The cutting simulation of soft tissue is important in virtual surgery. It includes three major challenges in computation: Soft tissue simulation, collision detection, and handling, as well as soft tissue models. In order to address
the earlier challenges, we propose a virtual cutting system based on the mass-spring model. In this system, MSM
is utilized to simulate the soft tissue model. Residual stress is introduced to the model for simulating the shrinking
effect of soft tissue in cutting. Second, a cylinder-based collision detection method is used to supervise the collision
between surgical tools and soft tissue. Third, we simulate the… More >
