• This study was performed as a part of the research on the ultrasonic measurement of bone porosity, bone density, and Young's modulus. It was found that the bone porosity estimated by Biot's theory agrees within 5% of the actual porosity. The bone's structure factor involved in the Biot's theory was determined experimentally to have a value of 2. It was also found that the use of the propagation velocity of the fast wave is more advantageous than using the slow wave in estimating bone porosity. The estimated bone density obtained by the use of Biot's theory is within ±5% of the measured value obtained by the use of Archimedes' principle. Bone density as well as Young's modulus can be estimated precisely by using the proposed ultrasonic wave method.
