摘要: A novel interactive virtual needle insertion simulation is presented. The model simulates three-degree-of-freedom motion, physically-based forces, linear elastostatic tissue deformation and flexibility for the planning training of percutaneous therapies procedures. To validate approach, an experimental system measuring planar during insertions has been developed real-time algorithm allows users to manipulate as it penetrates a model, while experiencing steering torques lateral forces through haptic interface. Efficient numerical computation techniques permit fast relatively complex two-dimensional three-dimensional environments at control rates.
