N2 - Digital radiography is becoming one of the common radiographic testing techniques in various industries. However, to apply this new technique to nuclear components, one big issue is how to evaluate the images and ensure that the images have enough quality to be used as inspection record. In film radiography, the IQI, which stands for Image Quality Indicator, have been used to ensure that the films have enough quality to detect any specified defects in the products. In this paper, new alternative IQI that was developed in our previous study for digital radiography to evaluate digital image quality is tested and evaluated. In addition, new image evaluation criteria are also developed and evaluated by calculating MTF, which stands for Modulation Transfer Function, from the IQI images of the products. Finally, the recommended procedures to evaluate radiographic testing image are summarized.
