Abstract

The axial transmission technique is used clinically for cortical bone assessment. However, the ultrasonic propagation in this multiscale transverse isotropic medium remains unclear, because of the heterogeneous nature of cortical bone. At the macroscopic scale, the distribution of porosity induces a gradient of material properties oriented in the radial direction. The aim of this work is to evaluate the effect of a spatial gradient of material properties on the ultrasonic response of a transverse isotropic bone structure.
