基于RAM的磁共振成像设备的维护管理的研究

Research on Maintenance Management of Equipment of Magnetic Resonance Imaging Based on RAM

目的 为了优化磁共振成像设备维修维护质量管理,保障其临床使用质量和安全。方法 通过磁共振报修系统采集三年内某磁共振成像设备的故障发生时间和故障修复时间的相关数据,从而进行可靠性、可用性和可维护性(reliability,availability and maintainability,RAM)研究分析。结果 可靠性分析结果显示,通信模块为磁共振成像设备的关键子系统。可用性分析结果显示,射频模块是磁共振成像设备的关键子系统。可维护性分析结果显示,该磁共振成像设备因维护相关问题而未得到充分利用的比例为2.58%,为了提高磁共振成像设备的可用性,应缩短磁共振成像设备的维修时间。结论 基于RAM的磁共振成像设备分析,可帮助医院设备管理者开展磁共振成像设备的运行优化、维修策略制定和安全管理等工作。

Objective To optimize the maintenance quality management of MRI equipment and ensure the quality and safety of its clinical use. Methods The data of failure time and repair time of a MRI equipment in three years were collected by magnetic resonance repair report system, and then the reliability, availability and maintainability(RAM) were studied and analyzed. Results The results of reliability analysis showed that the communication module was the key subsystem of the MRI equipment. The results of usability analysis showed that RF module was a key subsystem of MRI equipment. Maintainability results showed that the proportion of the MRI equipment not fully utilized due to maintenance-related problems was 2.58%. In order to improve the availability of MRI equipment, the maintenance time of MRI equipment should be shortened. Conclusion RAM-based analysis of MRI equipment can help hospital equipment managers to carry out the work of operation optimization, maintenance strategy formulation and safety management of MRI equipment.
