title: Quality control in mammary radiography.
abstract: The doses, the image qualities and the factors affecting these were determined for all equipments used for mammary radiography in Finland. It was found that the quality of the equipment tested varied greatly. This is particularly well illustrated by the 5 000-fold difference between the highest and lowest surface doses. Large differences in image quality were also found.
