Assessment of Image Quality of Negative- and Reversal-Processed Medical X-Ray Films with Intensifying Screens by Entropy Method
スポンサーリンク
概要
- 論文の詳細を見る
The image quality, mainly from the viewpoint of granularity, of negative- and reversal-processed X-ray films with intensifying screens was assessed by the entropy method using two types of screen-film system. It was found, from the transmitted information (TI) or the relative efficiency of transmission η versus the relative exposure and density, that optimum conditions under which TI or η is a maximum exist for both negative and reversal X-ray films. It was also shown, from the conditional entropy H_x(y) which refers to granularity, that negative and reversal systems have better and poorer regions and that reversal systems are better at higher exposures than negative systems. This was confirmed by measuring the Wiener spectra.
