Objective: To investigate the repair method of Toshiba Aquilion 64-row CT artifact. Methods: Analyze the causes and maintenance methods of the artifact failure of Toshiba Aquilion 64-slice CT, and summarize the scientific and practical troubleshooting measures. Results: The Toshiba Aquilion 64-slice CT striping artifact and ring artifact were mostly caused by hardware, program failure or error operation. They could be eliminated layer by layer, adjusted for the direction offset, and corrected and improved the data acquisition and processing system Repair. Conclusion: Scientifically effective and reasonable operation can effectively improve the safe utilization rate of Toshiba Aquilion 64-slice CT, reduce the probability of the occurrence of artifact failure and give full play to its clinical practical value so that it can better serve the clinical patients.
