Finite element modeling of anatomical structure

Abstract

A system and method is provided for generating a finite element (FE) model of an anatomical structure based on a fitted model of the anatomical structure and association data. A segmentation model may be provided for segmenting the anatomical structure. Association data may be obtained which associates a segmentation model part of the segmentation model with a mesh property, the segmentation model part representing a pre-determined anatomical region of interest. The segmentation model may be applied to a medical image of a subject, thereby obtaining a fitted model providing a segmentation of the anatomical structure. The finite element model may then be generated based on the fitted model and the association data, said generating comprising meshing a finite element model part of the finite element model in accordance with the mesh property, the finite element model part corresponding with the pre-determined anatomical region of interest. Advantageously, this may result in an efficient generation of the FE model needing fewer manual iterations and/or alterations in the model or in the mesh.
