Simulating the behavior of elastic objects is an important research in the field of virtual reality. Visual simulation of soft tissue deformation is the core part of the surgery simulation system. However, there is not a uniform deformable model. To choose a suitable model for surgery simulation, a classification of deformation models is offered in this paper. The deformable model can divide into...
Surgery simulation system can provide a safe virtual training environment. Cutting of soft tissue plays a very important role in the system. During the operation, the soft tissue exhibits nonlinear property and topology change of the operated tissue usually causes the failure of the pre-computed quantity. The above reasons make the simulation of the real-time cutting a challenging task. This paper...
In this work we present PhyNeSS - a novel physics-driven neural networks-based surgical simulation system which, for the first time, combines the complexity and accuracy of physics-based non-linear soft tissue models and commercial finite element codes with the high speed of execution of machine learned neural networks. While soft tissue is inherently nonlinear, physics-based simulation of nonlinear...
