To use the critical angle reflection measurement method of ultrasonic detection of bone quality rapid and accurate

摘要

The present invention, simultaneous detection of critical angle reflection value of 2 or more of the ultrasonic wave from the target by using (10) an ultrasonic transducer including (16a, 16b) and receivers of two or more transmitters (12), By calculating the elastic modulus of the target (24), devices for determining the coefficient of elasticity of the target (24), is a method and system, and determined.
