The medical training systems based on virtual simulation are highly desired since minimally invasive surgical techniques have become popular to patients. The training system helps surgeon trainees to acquire, practice and evaluate their surgical skills, and the key component of such a system is to simulate the dynamic procedure such as 3D biological tissue deformation in surgical operation. In our...
A challenge in virtual reality based laparoscopic cholecystectomy simulation is to construct a fast and accurate deformable gallbladder model. This paper proposes a multi-layer mass-spring model which can adapt well to the built-in accelerating algorithms in PhysX-engine of GPU. The gallbladder is first segmented from clinical CT images. A multi-layer model based on the anatomical structure of gallbladder...
As minimally invasive surgical techniques become widely available to patients, medical training systems based on virtual reality (VR) are highly desired. These systems help surgeon trainees to acquire, practice and evaluate their surgical skills. A key component in a VR-Based training system is to simulate the dynamics that occur in surgical procedures. Tissue deformation, as a most common phenomenon...
