Abstract: Contrast-enhanced image data of breast tissue to be examined is generated. First two-dimensional contrast-agent-influenced x-ray projection data of the breast tissue are acquired at a first x-ray beam energy and a two-dimensional image data record is generated on the basis of the first two-dimensional x-ray projection data. Second two-dimensional contrast-agent-influenced x-ray projection data are acquired from different projection angles at a second x-ray beam energy that differs from the first x-ray beam energy and a three-dimensional tomosynthesis image data record of the breast tissue is reconstructed from the detected second two-dimensional x-ray projection data. Subsequently, a two-dimensional synthetic mammogram is calculated on the basis of the three-dimensional tomosynthesis image data record and a two-dimensional dual-energy mammogram is established by subtracting the image data of the synthetic mammogram from the image data of the two-dimensional image data record.

Abstract: 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.
