Quality Imaging — Comparison of CR Mammography with Screen-Film Mammography

The aim of this work is a quality imaging comparison of CR mammography images printed to film by a laser printer with screen‐film mammography. A Giotto and Elscintec dedicated mammography units with fully automatic exposure and a nominal large focal spot size of 0.3 mm were used for the image acquisition of phantoms in screen‐film mammography. Four CR mammography units from two different manufacturers and three dedicated x‐ray mammography units with fully automatic exposure and a nominal large focal spot size of 0.3 mm were used for the image acquisition of phantoms in CR mammography. The tests quality image included an assessment of system resolution, scoring phantom images, Artifacts, mean optical density and density difference (contrast). In this study, screen‐film mammography with a quality control program offers a significantly greater level of quality image relative to CR mammography images printed on film.
