Abstract :
In medical imaging research fields, three-dimensional (3D) shape modeling and analysis of anatomic structures with fewer parameters is one of important issues, which can be used for computer assisted diagnosis, surgery simulation, visualization and many medical applications. The 3-D object shape or surface can be expressed by spherical harmonics. In this paper, we present a spherical harmonics based 3-D shape modeling for spleen and evaluate its shape reconstruction accuracy. Spherical harmonics modeling (SPHARM) is a smooth, accurate fine-scale shape representation and given sufficiently small approximation error.
