Abstract：Objective To study which DR performance parameters should be frequently tested by medical institutions, so as to realize
mutual recognition and sharing of medical images Methods Some common DR equipment that was normally used in medical
institutions were selected, and relevant performance parameters were tested referring to the national metrological verification
regulation JJG 1078-2012 medical digital photography (CR, DR) system X-ray radiation source for testing relevant performance
parameters. Then, statistical analysis was conducted on the data. Results The main performance parameters that affected the quality
of DR imaging were spatial resolution and low contrast resolution. Conclusion In order to realize mutual recognition and sharing of
medical images, it is suggested that medical institutions should often test the spatial resolution and the low-contrast resolution.
