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. I...

Acute mesenteric ischemia is a life threatening disorder that requires early diagnosis and timely management. With the development of MDCT technology, role of CT in this field has dramatically expanded. Acute mesenteric ischemia can be caused by various conditions such as arterial-occlusion, venous-occlusion, non-occlusive mesenteric ischemia and s...

Since the medical training samples are very limited, it is difficult to construct a statistical shape model with good generalization using few samples. In this paper, we propose a novel statistical shape modeling method using 2D PCA. The 3D shape is represented as a matrix by spherical parameterization. The experiments showed that our proposed meth...
