%X The curve with the Image Quality Indicator (IQI) for the optimizing function was inferred in this paper.The influecing parameters of the IQI were studied and optimized.Based on the optimizing theory and experiments,and with the iron thickness as a self-parameter,the exposure curve was obtained using best parameters during the Digital Radiography (DR) testing.The curve will improve the DR tesing technology.
