TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS 1 Real - time elastic deformationsof soft tissues for surgery
In this paper, we describe a new method for surgery simulation including a volumetric model built from medical images and an elastic modeling of the deformations. The physical model is based on elasticity theory which suitably links the shape of deformable bodies and the forces associated with the deformation. A real-time computation of the deformation is possible thanks to a pre-processing of ...
متن کاملReal-time simulation of biological soft tissues: a PGD approach.
We introduce here a novel approach for the numerical simulation of nonlinear, hyperelastic soft tissues at kilohertz feedback rates necessary for haptic rendering. This approach is based upon the use of proper generalized decomposition techniques, a generalization of PODs. Proper generalized decomposition techniques can be considered as a means of a priori model order reduction and provides a p...
متن کاملAccounting for large deformations in real-time simulations of soft tissues based on reduced-order models
Model reduction techniques have shown to constitute a valuable tool for real-time simulation in surgical environments and other fields. However, some limitations, imposed by real-time constraints, have not yet been overcome. One of such limitations is the severe limitation in time (established in 500Hz of frequency for the resolution) that precludes the employ of Newton-like schemes for solving...
متن کاملA Hybrid Elastic Model allowing Real - Time Cutting , Deformations and Force - Feedback for Surgery Training
We propose three diierent physical models based on linear elasticity theory and nite-elements modeling that are well-suited for surgery simulation. The rst model combines pre-computed deformations to deform in real-time large size meshes but does not allow any topo-logical changes to the mesh. The second model is similar to the spring-mass models where volumetric deformations and cutting operat...
متن کاملThe Framework for Real-Time Simulation of Deformable Soft-Tissue Using a Hybrid Elastic Model
In this paper, we present a novel approach for real-time simulation of deformable soft-tissue. The framework includes segmentation of medical data, physical and mathematical modeling, performance optimization as well as collision detection. The physical and mathematical modeling which is the most significant phase in the approach is based on an improved elasticity theory which uses the skeleton...
