Abstract

A range of model DQE calculations illustrates the detailed influence of the most important screen-film parameters. The screen is characterized by typical values for the primary x-ray absorption, spread function associated with secondary photons, and statistics associated with the gain of the conversion process. An existing film DQE model is used to explore the effect of film parameters on screen-film performance. Examples are given of the conditions under which screen-film DQE becomes independent of both film DQE and screen-film MTF. The influence of all these factors on system performance is discussed.
