Objective: To analyze and research detection data of radioactivity performance of digital radiography(DR) equipment so as to provide reference for purchasing DR equipment in hospital. Methods: Through collected the analysis results of detection data of quality control of 153DR equipment of third level 1 st class hospital, third level 2 nd class hospital and county level hospital of Yunnan province. The comparison analysis about these DR equipments depended on the hospital type, nationality of equipment and duration of service. Results: There were 50 DR equipment and 103DR equipments in the third level 1 st class hospital and the third level 2 nd class hospital, respectively. And in the third level 1 st class hospital, there was 79.17% of DR equipments was imported equipment, while it was 51.45% in the third level 2 nd class hospital. Besides, the duration of service of the most of DR equipments was 0-4 yeras in the third level 2 nd class hospital, while it was 5-7 years in the third level 1 st class hospital. Conclusion: Most of the DR equipments in the third level 1 st hospitals are imported equipment, and their duration of service were longer. On the other hand, in the comparison between imported equipment and domestic equipment, there are a certainly gap in quality stability, reliability and other aspects.
