| Research Abstract |
We tried to develop a simple osteoporotic diagnosis device based on speed of sound(SOS) through calcaneus using ultrasound. Specifically, after attaching the probes to both sides of heel and measuring the heel surface temperature, the echo wave form transmitted through heel was measured. From these results, the SOS through calcaneus was calculated precisely by assuming the calcaneus width as the 64% of heel width, and by considering the influence that the heel temperature exerts on the SOS through heel. It was established the measuring technology that my SOS result was more accurate than that of other companies. Furthermore, the commercialization of the very low price diagnosis device is under way in the enterprise on the basis of my research results.
