Abstract :
A new acoustic technique based on stress wave propagation is developed to diagnose, in a novel noninvasive way, bone abnormalities in vivo. The stress wave is generated with the help of an electromechanical vibrator and is passed through the bone at one end and is monitored at the other end with the help of a microphone pickup in terms of an electrical signal. The technique is found to be useful in the noninvasive diagnosis of bone fracture healing. It overcomes the difficulties faced in conventional techniques
