| Abstract: | Objectives The AMSAA model was applied to analyze the failure interval of the large-scale medical equipments,in order to enhance the predictability of the failure of medical equipments.These process undertake the preventative maintenance,and ensure the normal operation of the devices. Methods Collected the failure record of 3T MRI in the X-ray department of a large general hospital in WuHan for 120 days,used the paper to fit AMSAA model. Results The Mean Time Between Failures（MTBF） of 3T MRI in this hospital was 7.99 days. Conclusions This study could effectively estimate MTBF through AMSAA model,which provided scientific reference for preventive maintenance for medical machine. |
