Abstract
The objective of this study is to show the feasibility of long bone imaging using ultrasonic tomography. Ultrasonic propagation in bones suffers from the severe mismatch between the acoustic properties of this biological solid and those of the surrounding soft medium, (soft tissues in vivo or water in vitro. This propagation depends on the skeletal site we are analysing, which is more or less heterogeneous and anisotropic. Because this study is a new approach to ultrasonic bone examinations, the skeletal site that we have been investigating corresponds to the cortical zone of the femur (the diaphysis) where the biological structure was considered weakly heterogeneous beside the wavelength and isotropic to the perpendicular plan of the vertical fibres.
