Development of dynamic EMG scanning signal generator / 中国医疗器械杂志

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, but also has superior capability of stabilization and credibility than the same product.
