Abstract

While the design of commercial film screen systems often arrives at optimal or near optimal signal-to-noise performance, the process for achieving these optima is often arduous and expensive. Moreover, while the signal-to-noise ratio is optimized, it is often difficult to predict the optimum signal level for a given class of diagnoses. We have devised a digital system which, by performing calculations on digitally stored `baseline' phantom images recorded by a low speed x ray exposure on a wide dynamic range x-ray film, allows us to optimize system performance and to specify the design of film/screen systems for different classes of diagnostic images before screens and films are actually coated. We describe the application of this model to the development of an optimized system for chest radiology.
