Abstract

Digital radiography is getting one of the common radiographic testing techniques in various industries now. However, to apply this new technique to nuclear components radiographic testing, one big issue is how we can evaluate and ensure that the taken images have enough image qualities to be used as inspection record. In film radiography, the IQI, which stands for Image Quality Indicator, have been used to ensure that taken films have enough quality to detect any specified defects in the products. So in this paper, new alternative IQI that developed in our previous study for digital radiography to evaluate digital image quality are tested and evaluated. In addition, image evaluation criteria are also developed and evaluated by calculating MTF, which stands for Modulation Transfer Function, from the IQI images taken with the products. Finally, the recommended procedures to evaluate radiographic testing image are summarized.
