Abstract:
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.
CONCLUSIONS: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.
