Abstract

In this paper, a volumetric model of the left human ventricle has been built using a coarse Finite Element mesh with a finer surface mesh obtained from the human patient SPECT data. Using this approach real time haptic interaction can be achieved which is essential to many interactive applications such as surgery simulators. The dynamic behavior of this volumetric 3D deformable model is based on linear elastic theory. Temporal evolution of the model is solved using a semiimplicit Euler scheme to integrate the Newtonian dynamics. Both speed and stability are improved with this approach.
