<p>A bone assessment apparatus for assessing bone by ultrasonic waves. A slider mechanism (23) for supporting a platform (22) is provided such that it is free to be given a parallel displacement (104). When a foot is placed on the platform and a pair of measuring units (26A,26B) are brought close together, the platform starts to slide when one of the units comes in contact with the foot. When the contact pressures of the two units are identical, the sliding motion stops. The center line of the foot is thereby made to coincide with the center line between transducers, and in this situation, ultrasonic waves are transmitted and received.</p> |
