Abstract :
It is now commonly accepted that the spatial architecture as well as the multiphasic nature of a medium strongly influence the propagation of ultrasonic waves. Using a model-based approach, the propagation of acoustic waves in spongy bone tissues was analyzed within the framework of the Biot´s theory. Both theoretical analysis and experimental tests demonstrated the existence of two different longitudinal modes in human and bovine bony tissues
