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 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 کاملThree-dimensional surgical simulation for facial asymmetry: soft tissue-, skeleton-, and occlusion-based planning
Using three-dimensional (3D) computerized simulation systems has enabled us to determine the anticipated position of the maxilla and mandibular proximal and distal segments. The bony segments need to be mobilized according to the planned final position. The concept of 3D surgical planning in orthognathic surgery has evolved continuously. While using 3D simulation for planning the correction of ...
متن کاملA framework for Soft-tissue Deformation
For the simulation of soft tissue deformation Finite Element Method (FEM) has been the technique which achieves most physically realistic behaviour. However to provide stable force feedback, high refresh rates are needed which makes the use of FEM non-trivial. To solve the challenge of the compromise between speed and realism, asynchronous regions which solves different parts of the model with ...
متن کاملMeshless algorithm for soft tissue cutting in surgical simulation.
Computation of soft tissue mechanical responses for surgery simulation and image-guided surgery has been dominated by the finite element (FE) method that utilises a mesh of interconnected elements as a computational grid. Shortcomings of such mesh-based discretisation in modelling of surgical cutting include high computational cost and the need for re-meshing in the vicinity of cutting-induced ...
