动态肌电扫描信号发生器的研制

Development of Dynamic EMG Scanning Signal Generator

本文介绍一种以单片机为核心的动态肌电扫描信号发生器,可用于动态的功能磁共振以及运动肌肉的表面肌电特征研究等领域。它利用光纤以及光电开关,实现在强电磁场环境下为CT机扫描提供心电触发信号,其信号的发生与被扫描肌体的运动之间的延时可以任意调节。结果表明,该发生器功能齐全,操作简单,稳定可靠,功能优于进口的同类产品。

Development of a dynamic EMG scanning signal general based on microcontroller is introduced to be used in such fields as research of dynamic magnetic resonance scanning and moving muscle surface EMG.Optical fiber and photoelectrical switch are applied to work in strong electromagnetic environments to produce trigger signal which is similar to ECG.The occurrence of signals and the activity of the scanned bodies can be delayed at will.The results show that it not only has complete functions,simple operation,b...
