摘要
超声骨密度仪可以很好地对人体的骨质疏松程度进行测量,具有无放射性、廉价等优点。从硬件和软件两个方面讨论了基于超声传感器的骨密度仪的设计,主要包括超声发射、超声接收、信号处理以及嵌入式平台的搭建,骨密度仪判定标准T值和Z值数据库的建立。从实际测试结果验证了此设计方案的可行性。
Ultrasound bone density instrument is a good measure of osteoporosis for the human body. The instrument has the advantages of no radioactivity, low cost and so on. The design of bone density instrument based on ultrasonic sensor is discussed from hardware and software, including ultrasonic emission, ultrasonic reception, signal processing, the establishment of embedded platform, and the construction of the standard T value and Z value database. The feasibility of this design scheme is verified from the actual test results.
