Abstract: Objective To analyze the defect of examining flow in the digital radiography of the radiology department and root causes of failure images, and explore the corresponding measures to ensure the radiation safety of the subjects.Methods The failure mode and effect analysis and root cause analysis were used to analyze the examining flow and the cause of failure images stored on the DR machine before making corresponding corrective measures. Compare the incidence of failure images and the risk priority number after implementing the corrective measures.Results The incidence of the failure images reduced to 0.29% from 0.95% after implementing FMEA and RCA with statistically significant difference (x2=265.5, P<0.05). The risk priority number declined significantly, especially for the fifth examining flow, it reduced by 62.50%.Conclusion The management on the radiation safety of the digital radiography with the application of FMEA and RCA can effectively reduce the incidence of failure images and the risk priority number in the examining flow, which could decrease the potential risk of ionizing radiation on the subjects.
