title: Image quality of an image-intensifier fluorographic system.
abstract: For an image-intensifier fluorographic system, all essential image-quality parameters (such as MTF, noise Wiener spectrum, sensitivity, and characteristic curve) were determined. The results are in good agreement with theoretical considerations and allow a specification of the influence of the system's components on image quality. Film noise especially, because of the small image format, is of much more importance than had been assumed. A formula for the adjustment of system sensitivity (optimum input dose) has also been derived.
