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

TLDR
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.

Toward realistic soft-tissue modeling in medical simulation

TLDR
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.

TLDR
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.
