  • Title: Comparison of the low-contrast detectability of a screen-film system and third generation computed radiography.
    Author: Cook LT, Insana MF, McFadden MA, Hall TJ, Cox GG.
    Journal: Med Phys; 1994 May; 21(5):691-5. PubMed ID: 7935205.
    Abstract:
    Contrast-detail (CD) analysis was used to compare the low-contrast detectability of computed radiography (CR) and screen-film (SF) as applied to the task of adult chest radiography. A phantom was constructed and imaged using the same exposure factors throughout all experiments. Within-observer variance, between-observer variance, and image sample variance were calculated and used to estimate the standard error for each experiment. The results of these CD experiments agreed with the predictions of the Rose model. Observers performed equally well for low-contrast target detection using CR and SF.
