Abstract Objective To analyze the results of ranging error detection and discuss its influencing factors, so as to control the imaging link of DR detector.Methods Referring to “the medical digital X-ray photography (DR) system quality control test specification ”(WS 521—2017), the DR ranging error detection results were processed. Meanwhile, DR equipments from the same manufacturer were selected for horizontal comparison and those from different manufacturers for vertical comparison.Results The overall qualification rate of DR ranging error was not high, with an average qualification rate of 63.6%. The qualification rate reached 100% after ranging correction.Conclusion Further refinement of detection methods and reduction of data acquisition errors can effectively improve the qualification rate of ranging errors, which is of great significance to medical X-ray image diagnosis.
