Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a novel multiple level sets method based on minimization of energy function taking into account hierarchy, exclusiveness, and filling factor of organs. Energy relating to hierarchy of organs is defined as overlapped volume with outside regions of abdominal cavity and energy associated with exclusiveness is designed based on overlapped volume with neighboring organs. Energy of filling factor of organs is expressed through uncovered volume with other organs. To avoid over-extraction of outside areas of organs, we also introduce uniformity of gray values as additional energy terms. Speed function of level set functions to minimize the energy function is given by calculus of variations and linearly combined with previously proposed speed function. This paper also shows experimental results of applying the proposed method to actual CT images and discussion about effectiveness.
