PROBLEM TO BE SOLVED: To inexpensively search an artificial joint of the distal end of the thigh bone suitable for a subject compared to a search using an MRI or the like.
SOLUTION: A mechanical three-dimensional probe 10 is positioned in a predetermined positional relationship with respect to the knee bent largely by sitting on a chair or the like. An ultrasonic wave is then transmitted from the probe 10 to scan and acquire tomographic images of the inside of the knee including the distal end of the thigh bone. A profile extracting section 30 acquires profile lines of the medial condyle of the distal end of the thigh bone by binarizing each tomographic image. A loaded part cross section determining section 32 determines the profile line of the tomographic image located at the outermost side of the knee as a profile line of a loaded part of the medial condyle, and a diameter calculating section 34 calculates the diameter of the profile line. A matching joint searching section 36 then searches an artificial joint that matches the diameter from an artificial joint database 38.
