摘要
A method image scans a female breast in the context of projective digital mammography or tomosynthesis with prefiltered x-ray radiation. From a single scanning two spatially superimposing images are created on the basis of pixel-by-pixel or pixel-group-by-pixel-group different x-ray energy spectra. An x-ray mammography system contains a radiator-detector system having an x-ray tube with a filter for generating a prefiltered x-ray radiation having a first radiation spectrum and a radiation detector containing a multiplicity of partial areas which generate individual image pixels. The radiator-detector system is configured to the effect that the partial areas receive pixel-by-pixel or pixel-group-by-pixel-group different radiation spectra, such that the two images from different x-ray spectra are received with a single scanning of the female breast. Ideally, the detector is a pixilated x-ray detector with a converting sensor layer that is divided into at least two sets of partial areas, the sets having different thicknesses.
