Performance tests for mammographic film-screen combinations: use of absolute techniques

Abstract

PURPOSEA performance comparison of film-screen combination used in mammography was conducted using conventional and new techniques.RESULTSConsidering the image quality scores from three observers and the radiation doses obtained from the speed measurements, eight combinations were selected as being optimal. Only three of the mammographic film screen combinations in this group were the recommendations of manufacturers.CONCLUSIONThe total performance phantom can be effectively used for the qualitative check of image and provide speed information for mammographic film-screen combinations comparable to sensitometric techniques.
