Objective:
An improved failure mode and effects analysis (FMEA) model is constructed to enhance the accuracy of reliability assessment for wide-detector computed tomography equipment.
Methods:
A multidisciplinary expert panel is established. A scoring system is used to quantitatively evaluate various potential failure modes, and expert weights are introduced for weighted calculation to achieve objective ranking of risk priority.
Results:
The overheating of the X-ray tube and system communication interruption are identified as the highest-risk failure modes. Significant differences in equipment reliability under different clinical usage patterns are quantitatively revealed.
Conclusion:
The improved FMEA method can effectively identify key failure links, providing a reliable basis for formulating differentiated and precise preventive maintenance strategies, which is helpful for ensuring the continuous and stable operation of equipment.
