The virtual surgery planning and simulation tools have gained a great deal of importance in the last decade in a consequence of increasing capacities at the information technology level. The modern hardware architectures, large scale database systems, grid based computer networks, agile development processes, better 3D visualization and all the other strong aspects of the information technology brings necessary instruments into almost every desk. The last decade’s special software and… 

Real-time deformation simulation of non-linear viscoelastic soft tissues

A new hybrid technique is proposed that acts on the reduced order static model acquired through the model reduction technique known as Karhunen—Loéve (KL), and the dynamic behavior is obtained by overlaying pre-calculated displacement responses of surface nodes accounting for the time-dependent viscoelastic properties.

The aim of this work is to describe the main components necessary for a realistic haptic feedback in surgery, concentrating on the modelling of soft organic tissue, necessary for the simulation of soft tissue deformation.

Development of surgical simulator with high-quality visualization based on finite-element method and deformable volume rendering

A surgical simulator running on a PC workstation is developed, which can realize both the display of fine structure, such as small vessels in an organ, and fast deformation computations using a finite-element method based on relatively coarse meshes.

Toward realistic soft-tissue modeling in medical simulation

The author surveys existing models of deformation in medical simulation and analyzes the impediments to combining computer-graphics representations with biomechanical models, and inspects the potential of medical simulation under the development of this key technology.

Improving realism of a surgery simulator: linear anisotropic elasticity, complex interactions and force extrapolation

The latest developments of the minimally invasive hepatic surgery simulator prototype developed at INRIA are described, including the implementation of several biomechanical models and the integration of two force-feedback devices in the simulation platform.

A multiresolution modeling technique is proposed, where a reasonably coarse global model is locally enhanced using mesh subdivision and smoothening using adaptive subdivision of the boundary element mesh, which results in interactive graphical as well as haptic rendering rates for reasonably complex models.

Anatomy-based facial tissue modeling using the finite element method
