WebRadiographic density is reflected by radiographic image darkness. In conventional film radiography, it is called "transmitted density" because it is a measure of the light transmitted through the film. In digital imaging, it refers to how much the overall histogram of the image is shifted towards the lower grey levels. 3, 6-8 WebRadiographic Density - the overall amount / degree of darkening on a radiograph. In routine radiography, the useful range of density varies from 0.3 to 2.0 density. The density below 0.3 is due to the density produced by the base and by some fog on the film (base plus fog). Density is primarily determined by mA - Board question.
