Modeling and Simulation of Soft Tissue Deformation
A stable and accurate deformable model to simulate the deformation of soft tissues is a challenging area of research. This paper describes a soft tissue simulation method that can deform multiple organs synchronously and interact with virtual surgical instruments accurately. The model we used in our method is a multi-organ system by point masses and springs. The organs that anatomically connect...
متن کاملDirect Computation of Nonlinear Soft-Tissue Deformation
A method for computing nonlinear soft–tissue deformation caused by simulated surgical procedures is presented. A mass–spring system is used to model patient individual soft–tissue. Instead of simulating dynamic behaviour, the introduced approach directly estimates the rest position of the system. Very fast and robust nonlinear soft–tissue deformation is computed using an optimization approach. ...
متن کاملSuite of finite element algorithms for accurate computation of soft tissue deformation for surgical simulation
Real time computation of soft tissue deformation is important for the use of augmented reality devices and for providing haptic feedback during operation or surgeon training. This requires algorithms that are fast, accurate and can handle material nonlinearities and large deformations. A set of such algorithms is presented in this paper, starting with the finite element formulation and the inte...
متن کاملSoft Tissue Modeling for Virtual Surgery Simulation
Nowadays on medical and healthcare areas, training and learning methods for surgeons are based on skills development. In order to improve this learning process, virtual reality simulators have been proposed due its capacity to reproduce surgical procedures without any risk or harm on patient. These devices represent a wide research area that involves multiple fields of knowledge, such as mechat...
