| Research Abstract |
In medical image analysis, the three-dimensional (3- D) shape representation and modeling of anatomic structures using only a few parameters is an important issue, and can be applied to computer assisted diagnosis, surgical simulations, visualization, and many other medical applications. In this paper, we propose an efficient shape representation method using spher- ical harmonic functions (SPHARM) for 3D anatomical structure such as the liver. We show that the 3D shape of the liver can be reconstructed by a few coefficients of the SPHARM. We also propose to use SPHAM based shape representation for statistical shape modeling. Since the dimension of SPHARM based shape representation vector is much lower than the conventional shape representation using coordinates of surface points, our proposed method can be used for small number of training samples and enhance the computation cost.
