Development of a patient-specific surgical simulator based on virtual reality

摘要

A surgical simulator can provide doctors with a new way to realize surgical planning and surgical training. In this study, we developed a surgical simulator based on virtual reality technology and haptic device, which can simulate drilling, cutting and catheterization in a virtual environment. The virtual spring model and collision detection algorithm are used to simulate the feedback force while the subdivision mesh algorithm, the voxel remove algorithm and the trajectory method are used in order to simulate the deformation of models in the surgical simulator. All the models are reconstructed from CT data of the patients, which allow the surgical simulator to be patient-specific.
