A portable electrocardio acquisition device for electrocardio gating system

Abstract

A portable electrocardio acquisition device for an electrocardio gating system, comprising: a portable electrocardio acquisition device main body, one end of the portable electrocardio acquisition device main body is provided with an electrocardio lead wire; the main body comprises a shell and an electrocardio gating circuit with electromagnetic interference suppression function arranged in the shell, and the electrocardio lead wire is connected with the electrocardio gating circuit. By combining the anti-saturation acquisition circuit with the dynamic filtering technology, the interference is greatly reduced, the high-frequency interference in the MRI environment is significantly reduced, the R-wave detection accuracy is ensured, the R-wave detection delay is extremely low, the MRI image resolution is improved, the influence of the MRI environment on the ECG signal is significantly reduced, the signal distortion is avoided, the real-time adaptive filtering is realized, the modular shell design takes into account the portability and electromagnetic shielding performance, the high-reliability electrocardio gating synchronization is realized, and the core problems of low sampling rate, large delay and easy signal saturation of the traditional ECG device in the strong electromagnetic field are solved.
