Abstract (in Japanese) (See Japanese page) 
(in English) We have studied the automatic segmentation of multi-organ region from abdominal CT images ever. In previous work, we have proposed the automatic segmentation of multiple organ region by performing a hierarchical statistical modeling using a relationship between organs. In this paper, we have proposed automatically segmentation of the upper digestive tract from abdominal contrast-enhanced CT using segmented multi organs so far. Segment and compare the esophagus, stomach and duodenum using hierarchical statistical modeling which is our proposed method, and conventional statistical atlas method. They were evaluated quantitatively by Jaccard index and the surface distance error of the segmented region and correct region data.
