Abstract :
A non-invasive method to measure bone integrity has been developed which has potential for monitoring osteoporosis. It is based on a patented process of obtaining the dynamic characteristics of the bone using dynamic excitation in the range of acoustic frequencies (a sound source). The Modal Damping Factor has been used as an indicator of the tendency of the bone to fracture. Results of numerous animal studies have supported this hypothesis
