Abstract
A method for assessment of bone properties utilizing a new set of ultrasound parameters comprises passing ultrasonic signal through a bone tissue, modeling an output signal and a reference output signal and subjecting said parameters of the models to comparative analysis. Some of the new ultrasound parameters can be determined using analog processing techniques. An apparatus is also disclosed for practicing this method with one embodiment utilizing multi-element, two-dimensional array transducers. In conjunction with said array transducers, a synthetic aperture array mode is also disclosed.
