Development of Ultrasonic Propagation Analysis Method for Estimation of Inner State of Bone Phantom

Abstract

The preliminary study on the ultrasonic pulse propagation in the bone is described in this paper. The proposed method concerns about not only longitudinal waves but also shear waves in the bone. A simple phantom composed of three materials is also proposed, because the cancellous bone has the trabecular bone and the bone marrow. Calculated results show that the characteristics of received pulse waveforms are affected by the contents of the trabecular bone. The experimental results agree with the calculated results
