飞利浦Ingenia 3.0 T磁共振成像仪射频系统故障三例

Three Cases of Radio-Frequency System Failure in Philips Ingenia 3.0 T MRI Instrument

磁共振成像无电离辐射且软组织成像效果较好,已成为常规体检和疾病诊断非常重要的医学影像诊疗技术之一。磁共振设备结构复杂,维修及维护成本较高,长期高负荷的运转会导致磁共振设备故障率增加。本文总结了本院飞利浦Ingenia 3.0 T磁共振设备射频系统故障三例,包括de-tuned印刷电路板故障、射频放大器故障及体线圈故障。文中对三例飞利浦磁共振设备射频系统故障的表现进行了描述,对故障产生的原因进行了分析并介绍了故障排除过程,包括观察外观、提取后台日志参数、测量疑似受损部件指标、更换受损部件以及系统测试。通过深入分析射频系统故障案例,分享维修经验,以期提高设备使用率。

Magnetic resonance imaging(MRI)has become one of the essential medical imaging diagnostic technologies for routine physical examinations and disease diagnosis,as it is free from ionizing radiation and performs well in soft tissue imaging.MRI equipment has a complex structure and high maintenance costs,and long-term operation at high loads increases the failure rate of MRI devices.This paper summarized three cases of radio-frequency system failures of Philips Ingenia 3.0 T MRI equipment in our hospital,including de-tuned printed circuit board failure,radio-frequency amplifier failure,and body coil failure.The paper described the manifestations of three cases of radio-frequency system failures in Philips MRI equipment,analyzed the causes of the failures,and introduced the troubleshooting process,including observing the appearance,extracting parameters from the backend logs,measuring indicators of suspected damaged components,replacing the damaged components,and conducting system tests.By conducting in-depth analysis of radio-frequency system failure cases,share maintenance experience so as to improve equipment utilization.
