| Abstract(in English) | Longitudinal ultrasonic wave propagation in bovine femoral cortical bone was investigated by using a conventional ultrasonic pulse system. First, we experimentally investigated anisotropy of longitudinal wave velocity in Axial-Tangential plane and Axial-Radial plane in three bovine cortical bones. The direction of the fastest wave velocity was a little inclined from the bone axis. Moreover, results from pole figure analysis indicated that there were small tilts of the HAp crystallites orientation. There was good correlation between the anisotropy of velocity and HAp crystallites orientation. However, a comparatively low correlation was found in the posterior parts, telling that velocity seems to be affected by not only the HAp crystallites orientation but also the microstructure. |
