ESTIMATION OF BONE STRUCTURE BY USING QUANTITATIVE ULTRASOUND TECHNOLOGY

摘要

PURPOSE: A method for measuring a bone structure using quantitative ultrasonic technology is provided to prevent a fracture due to an osteoporosis by using a correlation between an electric signal and a trabeculae of bone of a sponge bony tissue. CONSTITUTION: An ultrasonic wave generated by an ultrasonic converter(11) is irradiated to a sponge bony tissue. A transceiver(12) is used for driving the ultrasonic converter. A digital detection tube(13) detects the converted electric signal. A display unit(14) displays the electric signal. A phase speed and an attenuation coefficient of the electric signal are calculated.
