摘　　要：电磁兼容性(EMC)问题引起的磁共振图像伪影故障在磁共振设备中日益频繁和复杂,通过详细分析典型案例中磁共振成像(MRI)设备的电磁干扰源、耦合途径、敏感部件等故障原因,提出解决方案,以避免MRI设备伪影故障的发生。Magnetic resonance image artifact failures from electromagnetic compatibility(EMC)issues are increasingly frequent and complex in magnetic resonance equipment.Detailed analysis of electromagnetic interference sources,coupling paths,sensitive components and solutions of magnetic resonance equipment were presented through typical cases to provide reference for installation,maintenance,quality control and management of magnetic resonance systems.

关 键 词：电磁兼容性(EMC) 磁共振成像(MRI) 图像伪影 案例分析 质量控制
