Images of a contrast-detail phantom made with polymerized methyl methacrylate were acquired using screen-film (MinR2000/MinR2000) and full-field digital mammography systems with the same exposure conditions. Observer performance tests were conducted with participating eight observers. Each observer was required to identify a randomly located disk in phantom images with a 50% confidence level. Average contrast-detail curves for the digital and film images were obtained from the observation results. Image quality figures (IQF) were also calculated from the individual observer performance tests. The results indicated that the digital contrast-detailed curves and IQF are, on average, superior to those of the screen-film system.
