Abstract (in Japanese) (See Japanese page) 
(in English) Spinal curvature contributes to maintaining spinal balance, and maintaining normal spinal curvature is important. This study proposes a novel method which quantifies a spinal curvature in X-ray CT images. In this method, first, spinal canal is extracted on CT images, and a median plane image of spine is generated based on it. Second, spinal curvature is quantified using a vector method and PAL method on the median plane image. Three observers estimated the reproducibility of the Cobb method and the two proposed method. Experimental result showed the measurement value of the vector method had the variation smaller than the Cobb angle. Also, we confirmed the result value was reproducible by using PAL method. Therefore, a possibility that a vector method and PAL method could quantify for a spinal curvature was suggested.
