摘　　要：长期高负荷的使用导致磁共振设备故障发生率逐渐升高,对临床工程师迅速排除故障保障设备正常运行提出了更高的要求。本文对我院西门子MAGNETOM Avanto 1.5T磁共振设备发生过的发射器和RFSU电源故障、光纤断裂故障和PF信号线故障三例故障现象,逐步分析故障原因,通过更换Transmitter板和RFSU电源、光纤、PF信号线使设备恢复正常运行。本文旨在通过对这三个案例的分享,加强与同行的交流和学习,共同提高设备保障能力。Long-term and high-load use has gradually increased the incidence of magnetic resonance equipment failures,which has put forward higher requirements for clinical engineers to quickly troubleshoot and ensure the normal operation of the equipment.In this paper,three failures of the Siemens MAGNETOM Avanto 1.5T magnetic resonance imaging equipment,including transmitter and rfsu power supply failure,optical fiber break failure and PF signal line failure,were analyzed step by step.Then,the normal operation of the equipment was restored by replacing the Transmitter board and RFSU power supply,optical fiber and PF signal line.By sharing these three cases,we hope to strengthen communication and learning with peers and jointly improve equipment support capabilities.
