A comparison of two mammography film-screen combinations designed for standard-cycle processing.
This paper presents comparisons of the Kodak Min-R 2000 mammography film-screen combination designed for standard-cycle processing with that of the older Min-RM/Min-R combination. Comparisons were performed in terms of characteristic curves and relative image quality. The Min-R 2000 combination had a speed of 1.7 relative to the Min-RM/Min-R combination to yield an optical density of 1.25; the maximum gradients of the characteristic curves for the two combinations were 4.6 and 2.7, respectively. Image quality was evaluated in a breast detail phantom study. It was demonstrated that image qualities of the film-screen combinations were comparable.
