Ultrasonic wave propagation in stereo-lithographical bone replicas.

This work is to help scientists, researchers and/or medical practitioners etc., to understand the propagation of acoustic waves through cancellous bone, to understand what is affecting the wave propagation through the bones, and what kind of parameters of bone (porosity, tortuosity, viscous and thermal characteristic lengths, etc..) are mostly affecting the acoustic waves transmitting through bone. Medical practitioners can use the parameters affecting wave transmission through bone for early diagnose of the osteoporosis. Osteoporotic bones will have higher porosity values due to bone loss, so greater energy will be transmitted through them in comparison with normal bone.
