(57) [Summary] [PROBLEMS] To provide a method of measuring an index that reflects bone strength better than a measurement of bone density and a method of evaluating bone strength using the same. SOLUTION: An image obtained by using a means for imaging a continuous cross-sectional structure of a test bone is input to an image processing device, and the bone in the image is separated into a cortical bone region and a trabecular region. A bone strength evaluation method that calculates the volume, the maximum connected trabecular component volume, the number of trabecular sides, and the number of cavities, and uses the bone breaking force, maximum load, axial displacement, toughness, and maximum elastic force as indexes. |
