  • Method and apparatus for judging deformation of vertebral body
    Patent number: 5224035
    Abstract: A method for judging deformation of a vertebral body includes the steps of measuring a central length (a), rear brim length (c), and front brim length (d) from a profile X-ray image of a vertebral body to be judged, determining ratios of c/d, a/c and a/d, and classifying deformation of the vertebral body to be judged by using indices, c, d, c/d, a/c and a/d. Furthermore, a method for judging deformation of a vertebral body, which comprises obtaining at least two indices by measuring a central length (a), vertebral body width (b), rear brim length (c), and front brim length (d) from a profile X-ray image of a vertebral body, analyzing these indices by a discriminant function, and classifying a deformation of the vertebral body from results of the analysis.
