基于虚拟仪器技术的超声骨密度测量系统的设计

摘要

目的 文本设计了一个基于虚拟仪器技术的超声骨密度测量系统,用以评价骨质疏松.方法 首先基于LabVIEW虚拟软件平台开发程序,依据定量超声和通道复用技术实现超声波的发射和接收功能,然后通过NIUSB-6251数据采集卡采集相关数据,最终该软件平台实现资料输入、数据处理、结果 输出和保存,并进行系统测试.结果该系统可靠性高,操作方便简洁.结论 本系统在技术与应用层面上具有一定的创新性,从一种新的角度评估人体的骨质量,可应用于骨质疏松的早期诊断.%Objective This study designed an ultrasound measurement system of the bone mineral density (BMD) based on virtual instrument technology for osteoporosis diagnosis. Methods This system used the software LabVIEW to develop a program which could achieve the data input and processed, data output and save, with the basic theory of quantitative ultrasound and channel multiplex technology to accomplish ultrasonic transmitting and receiving function. This system used Data Acquisition Card NIUSB-6251 to transmit data. And then it was tested. Results It turned out that this system was reliable and easy to operate. Conclusion This system has highly innovation at the level of technology and application, which can be used for the early diagnosis of osteoporosis from a new angle.
