Abstract
This invention relates to a bone measurement method for measuring a bone shape, structure and architecture on the basis of the tomographic images of a test bone or joint, in more detail, to a bone measurement method characterized by having a template image extraction step for obtaining a wholly continued template image of a bone inner portion surrounded by a cortical bone from the binary image of a test bone cross section, and separating a cortical bone and a cancellous bone by the product of said template image and said binary image, as a bone measurement method which enables the automatic, high-speed and repeatable separation of a cortical bone and a cancellous bone on the basis of the binary image of a test bone or joint cross section and by which a separated three-dimensional image of the cortical bone portion and the cancellous bone portion is obtained as the bases for a non-invasive analyses of three-dimensional bone structure, bone strength, and the like.
