Surgical simulator systems have been developed for surgical training and planning. On the other hand, surgical navigation systems arise to play an important role in laparoscopic surgery. In these systems the deformation of organ is required to be simulated realistically. Finite element method is a useful tool for this purpose due to its clear physical background. In this work the simulation of liver deformation in liver surgery is carried out by introducing nonlinear finite element method. The material constants in the constitutive relation are identified by an experimental measurement, and then realistic deformations of liver are obtained by taking the geometrical and material nonlinearities into account.
