Abstract:: Abstract: Objective To explore the failure causes and intervention countermeasures of electron linear accelerators in clinical operation. Methods A retrospective analysis of the failure causes and frequency investigation results of a medical electron linear accelerator that was in clinical operation for fifteen months from September 2020 to December 2021, and effective intervention countermeasures were formulated. Results The common failure causes of medical electronic linear accelerators are mainly 21.82% (12/55) of X-ray volumetric imaging system failures, followed by 18.18% (10/55) of mechanical motion failures although the frequency of circuit failures is not high, Therefore, the function deactivation and downtime caused by the malfunction is relatively long. Conclusion In the clinical operation of medical electronic linear accelerators, in order to reduce the X-ray volumetric imaging system and mechanical motion failures, and reduce the frequency of failures, it is necessary to combine the causes and frequency of clinical operation failures of medical electronic linear accelerators to establish a regular effective intervention measures such as maintenance, in order to provide more high-quality clinical services for the majority of patients.
