PROBLEM TO BE SOLVED: To provide a method of simply and inexpensively evaluating a bone density and an ossein which are factors of bone strength by using ultrasonic wave.SOLUTION: A sonic velocity in a bone ( a finger or the like) is measured by using a single ultrasonic probe. A bone density or an ossein is evaluated from the measured ultrasonic propagation velocity in the inside of the bone which is taken over to a process of an evaluation method of the bone density or the ossein.COPYRIGHT: (C)2014,JPO&INPIT【課題】超音波を使って骨強度の要素である骨密度と骨質を簡便、かつ安価に評価する方法を提供する。【解決手段】一個の超音波探触子を使って骨(指など)の音速を計測し、骨内部の超音波伝播速度から、骨密度または骨質の評価方法の工程に引継ぎ、骨密度または骨質を評価する。【選択図】図3
