Abstract: The present invention provides a system for improving the accuracy of the measurement of the osteoporosis condition of the human body parts especially bones using more than three parameters, viz., the broadband ultrasonic attenuation (BUA) quantity, the velocity of ultrasound (SOS) in the bone, the broadband ultrasonic back scattering (BUB) intensity, and the Width of received maximum (WORM) values are calculated from received ultrasound signals. The accuracy of each measured diagnostic parameter is improved by measuring the tissue thickness and the squish amount in the coupling pad instead of assuming constant thickness for the tissue. The several operating modes of the device are controlled and the frequency and the timing of the emitted ultrasounds signals are adjusted by using a field programmable gate array. The error generated in the measurement of the bone mineral density due to the variation in the anatomy and the size of the foot, is removed by using a removable footpad.
