CLO016: Describe conditions that cause quantum mottle in a digital image.
Quantum mottle refers to the amount of exposure that reaches the image receptor. As the amount of photons that reached the image receptor decreased, the grainer the image or a pattern is superimposed upon the image. It can also affect the contrast resolution by concealing differences of the grey scale. To ensure that this doesn’t happen, the mAs or kVp must be increased as it will guarantee that an increased number of photons will reach the image receptor.
