Objective  To improve the maintenance efficiency of radiographic equipments to guarantee equipment operation with high quality. Methods Based on many years of various medical equipment maintenance practices, PICKER 6000CT machine and GE-AMX + mobile bedside X-ray machine maintenance for instance, the author analyzed the failure reasons and types. Results The failures were divided into five main types and five major reasons. The percentages of failure causes and types were obtained, and four medical equipment failure trends and seven measures to guarantee the quality and safety of medical equipment were summarized. Conclusions This research will be helpful to improve the equipment efficiency of the utilization and maintenance to reduce the medical expense.
