English: Images of a pelvic phantom demonstrating the dynamic range of CR. The image on the left is taken using 2 mAs and the one on the right using 160 mAs. The major discernible difference is the marked increase in quantum mottle associated with the low exposure image (e.g. examine the variation in pixel values in the region shown arrowed).
