Abstract
Detectors of computed radiography systems have a very wide linear dynamic range Pnd enable faithful acquisition of image data, independent of the chosen x-ray exposure or the dynamic data range within the image. To yield consistently viewable images of satisfactory quality without direct user interaction with the image, semi-automatic scaling of the clinically useful data span to the available display range must be achieved. Three methods are discussed: Detector auto-ranging and renormalization of the filtered image, local histogram equalization, and anatomy specific auto-ranging of the filtered image. Presently, the first method is favored and employed clinically.
