Effect of quantum mottle on radiographic image quality.

Pseudocirrhosis due to aggressive dose reduction techniques

Film graininess, nonuniformity of screen phosphor and quantum mottle contribute to overall radiographic mottle.[2] Of these three factors, quantum mottle is the dominant component and is the most important consideration regarding noise in the image.[3] Quantum mottle is defined as the statistical fluctuation in the number of photons per unit area that contribute to image formation.[4]

Quantum mottle becomes more pronounced when the number of x-ray photos absorbed in the screen is decreased, such as by reducing the radiation dose.
