Reconstruction tridimensionnelle d'éléments anatomiques et génération automatique de maillage éléments finis optimisés
Samuel Bidal · HAL (Le Centre pour la Communication Scientifique Directe) · 2003
The aim of this work is to quickly generate good quality models of the human body. We created a method package which generates finite element meshes from pictures of serial slices (taken from anatomic slices, X-ray scanner or MRI). The mesh generation is divided into three main steps : contours detection, 3D reconstruction and meshing. Contour detection methods were chosen to be applicable on a wide range of pictures. 3D reconstruction and meshing methods are new and based on an octahedral lattice. They allow generating quadrangular or hexahedral elements. The heads organs were chosen to validate the package. We studied other organs too but these works are just given here as examples.
