Abstract

This paper proposes a method for estimating patient-specific material parameters used in the finite element analysis which simulates soft tissue deformation. The estimation of suitable material parameters for a patient is important for a navigation system for endoscopic surgery. At first, many data of soft tissue deformation are generated by changing the material parameters. Next, using Principle Component Analysis, each data with high dimensional is converted into the lower vector. The relationship between the material parameter and the deformation is found in the lower potential space.
