一种基于单片机的胎心仪信号模拟装置
<p>胎心率是胎儿健康状态的重要生理指标,超声测量胎心率是临床上最常用的一种手段。在超声胎心仪的研制过程中需要胎心仪信号模拟装置来验证仪器精确性,提出一种基于单片机的胎心仪信号模拟装置,该装置用步进电机驱动小钢珠在水中震动,模拟人体内的胎儿心脏的跳动,通过单片机内的定时器功能改变钢珠震动的频率和幅度,通过震动的钢珠反射超声波,同时使用超声信号采集系统采集数据进行验证。结果表明该模拟器能够有效模拟胎

基于AR模型的HIFU无损测温方法研究
自回归功率谱密度(AR-PSD)方法的基础是生物组织的离散散射体模型〔超声体模〕理论,该模型认为生物组织为半规则的散射体分布的,这种方法是基于温度和频移的相关特性。本文介绍超声回波信号对HIFU(High Intensity Focused Ultrasound)治疗的测温技术,从测温模型和算法,实验仪器的设计和构建,仿真和离体实验中获取了一套有效的测温方法,利用Matlab7.1和VC++6.0

基于单片机的数字化B超键盘设计
<p>针对目前使用的RS232接口数字化B超键盘存在PC主机启动时不能设置BIOS,提出一种PS2键盘的设计方法。基于W78E052D单片机,采用8通道串行A/D转换器设计了8个TGC电位器信息采集电路,电位器位置信息以键盘扫描码序列形式发送,正交编码器信号通过XC9536XL转换为单片机可接收的中断信号,软件接收到中断信息后等效处理成按键。结果表明,在满足开机可设置BIOS同时,又可实现超声特有
