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 cutting operation with a three-stage cutting method with swept volume, B´ezier curve, and an algorithm named shortest distance nodes matching method. In order to verify the system performance, we carry out three validation experiments on the proposed system: Cutting accuracy experiment, collision detection validation, and practical cutting evaluation. Experiments indicate that our system can well perform the shrinking effect of soft tissue in cutting. The system has fast and accurate collision detection. Moreover, the system can reconstruct smooth incisions vividly.
