Abstract

Modeling of soft pelvic organs and their thicknesses is a difficult task, especially when inputs are noisy and scattered. In order to define the geometric step for a global pelvic surgery simulator, we define a new method based only on geometry while considering the problem of error transfer between outer and inner organ surfaces. We compare this approach with a parametric formulation and a mass-spring system.
