Abstract
This paper deals with Finite Element (FE) modeling of human body structures. More specifically, it focuses on the FE mesh generation process, which is a long and tedious task in the case of irregular and non-homogeneous structures. Whereas for regular and symmetrical bodies, some automatic mesh generators have been developed, no robust system is provided for living structures, which are, by definition, non-homogeneous, irregular and patient-specific. This paper proposes a new algorithm, called the mesh-matching (M-M) algorithm, that automatically generates patient-specific 3D meshes for FE models of structures with complex geometry. It assumes that the shape which is studied is sufficiently close to a known standard model for which a mesh has been already generated by an expert. The algorithm proposes then to use a registration method, in order to infer the standard finite element mesh to the data. The M-M algorithm is tested on five human femurs.
