Keywords: NoiseMottle.jpg en When an area of an image receptor is subdivided into small elements each element will absorb different numbers of X-ray photons because of statistical fluctuations in photon flux In the left hand matrix the average photon flux is 100 per unit area with a standard deviation of 10 leading to quantum mottle of 10 By increasing the photon flux by a factor of 100 the mottle may be decreased to 1 as shown in the right hand matrix own Kieranmaher 2001-01-01 Reproduced with permission from Heggie JCP Liddell NA Maher KP 2001 Applied Imaging Technology 4th Edition Physics diagrams
