Abstract

Since the two-wave separating phenomenon of ultrasound in cancellous bone was found, the detailed behavior of two waves has been investigated in order to put the mechanism into practical use. However, it has been unclear whether the two-waves could be seen in in vivo situation where the cancellous bone is surrounded by cortical bone which has complexed shape that may make the waveform unclear. Therefore, in this study, the ultrasound propagation in human radius-mimicking model was simulated using 3-D elastic FDTD method in MHz range. As a result, the two-wave separation was clearly seen. In addition, it is shown that the circumferential wave propagating inside cortical bone part arrives slower and had smaller amplitude than the fast wave propagating in cancellous bone. These results tells us that the fast wave might not be obstructed by the circumferential wave during in vivo measurement of radius.
