Abstract
The quality of radiographic images recorded by screen-film systems depends on the contrast and shape of the image detail which is of diagnostic interest. As a first approximation, the complex world of radiographic detail can be divided into two categories, one containing high contrast, inherently sharp detail (Class I), and the other containing low contrast, inherently unsharp detail (Class II). It is shown from test object and clinical radiographs that the image quality of Class I detail is affected mainly by the optical properties of the system and the image quality of Class II detail by quantum mottle. Therefore, the system MTF as well as receiver operating characteristic (ROC) curves are needed to evaluate radiographic image quality.
