Abstract

The paper presents a general non-rigid body representation for physically-based modeling of dynamic behaviour of heterogeneous objects and its application in a development of a new heterogeneous morphing technique to solve distortion correction problems arising in the medical data processing. The proposed representation provides a simply applicable tool for modeling of real medical objects allowing fast and reliable calculation of geometric deformations and simulation of dynamic behaviour in a heterogeneous environment when only a few initial landmark displacements are known.

The proposed method is applied in a distortion correction process of CT medical data sets, especially in an automatic processing of heterogeneous CT scans of human brain.
