Digital detector array (DDA) systems are becoming more prevalent in the industrial radiography market. Exposure conditions largely determine the imaging results that are obtained for a given system. New guidelines will require the establishment of a pixel intensity range to achieve acceptable contrast sensitivity. The sensitivity will depend upon the radiographic technique, material type, material thickness, DDA type, integration time, and the number of averaged frames. When the same pixel intensity has been obtained, it does not guarantee that the same contrast sensitivity has been achieved. This presentation presents experimental results that support these statements. It’s a myth that pixel values should be the same across a range of conditions. What really matters is the image quality, which determines the detectability of discontinuities.
