Design for ultrasonic diagnosis of osteoporosis based on ARM / 医疗卫生装备

ABSTRACT

Objective To develop a system for detection and diagnosis of osteoporosis by using quantitative ultrasound technology.Methods An ARM embedded system was used to measure the speed of ultrasound,the broadband ultrasound attenuation(BUA) and the stiffness.The speed of ultrasound mainly reflects bone structural features,BUA mainly reflects bone density,and stiffness can synthetically reflects bone intensity.Results Based on an ARM microprocessor,the whole system could diagnose osteoporosis through the parameters sent by ultrasound.Conclusion The system for ultrasonic diagnosis of osteoporosis based on ARM can achieve precise diagnosis in clinic by setting osseous parameters database of normal people in different age,weight and sex.
