Abstract (in Japanese) (See Japanese page) 
(in English) We had proposed an automated method of recognizing psoas major muscle in torso X-ray CT images using skeletal positional information, and confirmed that the method was effective to classify skeletal muscles, which was based on anatomical landmark recognition. The method used skeletal positional information and center line of skeletal muscle. However the method had issues that extraction rate of upper psoas major muscles was low. In this paper, we propose an improved method of psoas major muscle extraction using positional information of diaphragm. This is based on the idea that the diaphragm is closer to upper psoas major muscles. We applied this method to 15 cases,.and obtained the 10% increased concordance relative to previous method (81%); it was confirmed our proposed technique.
