【摘要】：为了提高超声骨密度仪性能,基于Visual C++2008 MFC实现上位机软件,实现测量结果稳定性和测量速度的改进,同时提高了超声声速(SOS)的测量精度。上位机软件包括界面设计、采集控制、数据处理与参数提取、数据存储以及报告打印等。设计了优良的人机交互(HCI)接口,操作便捷,可以实时观察波形。通过高效自动增益控制和有效数字滤波提高采集精度和稳定性。采用高速USB接口通信,向采集端发送控制指令,同时进行数据传输,有效缩短了测量时间。通过多通道统计平均测出超声声速和宽带超声衰减(BUA),结果稳定可靠。采用XML文档存储患者信息,检索方便。患者测量报告可实时打印。软件分层实现,便于维护与扩展。
[Abstract]:In order to improve the performance of ultrasonic absorptiometry, a host computer software based on Visual C2008 MFC is implemented to improve the stability of measurement results and the speed of measurement. The software includes interface design, acquisition control, data processing and parameter extraction. Data storage and report printing, etc. Excellent HCI interface is designed, which is easy to operate. The waveform can be observed in real time. The acquisition accuracy and stability can be improved by high efficiency automatic gain control and effective digital filtering. The high speed USB interface is used to communicate and send control instructions to the acquisition terminal and transmit the data at the same time. The measurement time is shortened effectively. The average ultrasonic velocity and broadband ultrasonic attenuation are measured by multi-channel statistics. The results are stable and reliable. XML documents are used to store patient information. The patient measurement report can be printed in real time. The software is layered and easy to maintain and extend.

【正文快照】： 引言我国人口基数较大,随着老龄化趋势增加,骨质疏松患者日趋增多。患者早期症状不明显,而病情严重后不仅容易发生骨折,还可能出现肺、心、肾等内脏并发症[1]。所以,定期测量骨质对于预防和及时发现骨质疏松有重要的指导意义。基于超声透射、反射、折射原理,定量超声检测技术
