| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We had proposed an automated method for recognizing skeletal muscle in torso X-ray CT images using skeletal positional information and shape model of its muscle, and confirmed that the method was effective in recognizing the muscles. The previous method recognized the muscle’s connecting points on the virtually unfolded image of the human body as landmarks and fitted a shape model based on the positional information obtained from the landmarks, to recognize the muscle region automatically. However, there was a variation in recognition accuracy at the site where the surface shape is greatly different depending on the difference in physique such as an abdominal region. In this paper, we have improved the virtual image-unfolding technique. The proposed method removed the subcutaneous fat area beforehand because of its significant difference by physique between patients, and applied the remaining regions for recognition of the muscle. We applied this methodology to 10 patients with no evidence of abnormalities to the rectus abdominis muscle. We achieved the 89% concordance with manual segmentation and confirmed the effectiveness of the muscle polyventer shape modeling and recognition. | |
