Method and device for the imaging scanning of a female breast in the context of digital projective mammography or tomosynthesis

An x-ray mammography system for imaging scanning of a female breast in a context of digital projective mammography or tomosynthesis, comprising:

• a radiator-detector system, containing:
• an x-ray tube having a filter for generating a prefiltered x-ray radiation with a first radiation spectrum;
• a radiation detector including a sensor layer for converting x-ray radiation into light or charge, said sensor layer divided into at least two sets of partial areas which generate individual image pixels, said sets of partial areas having different thicknesses, said sensor layer having a thickness structure defined by the different thicknesses;
• and
• compression plates including an upper compression plate and a lower compression plate, said compression plates configured for compressing the female breast during scanning;
• said radiator-detector system configured such that the partial areas receive pixel-by-pixel or pixel-group-by-pixel-group different radiation spectra, such that at least two imagings from different x-ray spectra are received with a single scanning of the female breast between said compression plates.
