Quantum mottle

Intrinsic X-Ray Absorption. The maximum amount of information coded in a radiologic image is limited, in part, by the statistical fluctuations of the x-ray photons that form the radiologic image (I). These fluctuations are often referred to as "quantum nois e and as "quantum mottle" when viewed on films since the films have a grainy appearance (I7 ). These fluctuations can be expressed as a signal to noise ratios (1. ... [Pg.208]

No easy comparisons can be made of commercial screens regarding quantum mottle, resolution and speed since different screen constructions are used and particle sizes differ. Other factors cannot be easily compared. The intent of the previous discussions was to compare several physical properties of rare earth x-ray phosphors which have an important effect on final image quality. Other benefits of rare earth screens include ... [Pg.215]
