Summary
| Description |
English: 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 |
