A method and apparatus of assessment of bone properties passes an ultrasonic signal through a bone tissue, modeling an output signal, a reference output signal, and subjecting parameters of the models to comparative analysis. The transducer (16) is used for signal launching and the transducer (18) is the receiver for the launched signals after passing through the bone part (10), its surrounding soft tissue (12) and coupling medium such as a gel between each transducer face, and the outer skin surface (14) of the soft tissue (12). Specifically, it is intended for non-invasive and quantitatively evaluating the status of bone tissue in vivo, as manifested through one or more of the quantities such as bone mineral density, strength, and fracture risk at a given time.
