Paper Abstract

Our aim is to elaborate 3D models to recover 3D deformable solids from few nonparallel 2D cross-sections. This problem is difficult when solids have time evolutive shape with no peculiarity (no symmetry axis for instance). Our application deals with cardiac ventricles, for which only three or four nonparallel 2D cross- sections are given from a classical echocardiographic examination. Three dimensional reconstruction of a solid consists in model deformation: it implies a matching between the model and data. This matching is generally global (or rigid) in a first step then local (or elastic) in a second step. The first step roughly matches model with data. The second one performs a more accurate matching. In this paper, we describe 2D deformable structures, then 3D deformable models.
