Abstract

A new and simple method by which the image quality of radiographs could be evaluated by a single number in terms of entropy was introduced by UCHIDA et al. in 1978, and applied to the problem of evaluating the performance of development processes [1]. This method of evaluation, which is termed the entropy method, has been applied to various problems in radiology [2–7]. In the present paper, the assessment of radiographic image quality or granularity of screen-film systems used in diagnostic radiology by a single number in terms of the entropy is described on the basis of our recent paper [4], and some considerations on the conditional entropy are made.
