Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a patient specific atlas for pancreas segmentation from three dimensional contrast enhanced CT images.
Unlike the conventional atlas, the patient specific atlas is constructed based on an estimated pancreas shape. The atlas construction process is followed by maximum a posteriori based segmentation. In this study, we propose a process that iterates from the shape estimation to the pancreas segmentation using the patient specific atlas for improving the performance. This paper shows the results of applying the proposed method designed by a training dataset to three phase contrast enhanced CT images of 20 unknown cases, and discusses its effectiveness by comparing the results with those of our previous method.
