Geometric modeling of living tissue for subject-specific finite element analysis

We introduce shape morphing approach to generate subject-specific finite element (FE) models. Different from the conventional approaches, our method generate individual (FE) model by applying spatial transformation to a reference model. It does not, therefore, require time-consuming works such as segmentation and mesh generation. The proposed method was applied to FE model generation of fingertips. The spatial trans-formation was computed using volume registration technique. The registration and the FE model morphing were carried out for two subjects. The morphing results showed good agreement in shape both for phalanxes and soft tissue.
