Abstract
A surface point tracked by an echo tracking processor unit for each ultrasonic beam is a tracking point. A strain measurement unit measures an amount of strain of a bone based on the surface points. A delay time measurement unit measures a time for the amount of strain of the bone to reach a return reference value, corresponding to a state before a load is applied, after the load is first applied to the bone and then removed.
