Abstract: In a method for producing a stereotactic image of a patient fixed in a mammography device for a biopsy, a computerized control and evaluation unit waits for a start signal to be given by an operator, and after receipt of the start signal, automatically implements the following steps. An x-ray apparatus of the mammography device is positioned in a first predetermined imaging position, and a first image of the patient is acquired with the x-ray apparatus in this position. The x-ray apparatus is then pivoted into a second imaging position, different from the first, and a second image of the patient is acquired at the second position. The first and second images are acquired to form a stereotactic image of the patient.

Abstract: A focus-detector arrangement of an X-ray apparatus is disclosed for generating projective or tomographic phase contrast recordings with a phase grating. According to at least one embodiment of the invention, in the gaps between its bars, the phase grating includes a filler material whose linear attenuation coefficient in the relevant energy range is greater than that of the bars. The height of the filler material in the gaps is dimensioned on the one hand so that the X-radiation with the energy used for measuring the phase shift generates a phase shift in the X-radiation such that, after the phase grating, the rays which pass through the bars are phase shifted by one half wavelength relative to the rays which pass through the gaps with the filler material. Further, the height of the filler material in the gaps on the other hand is dimensioned so that the attenuation of the X-radiation, at least in relation to the energy used for measuring the phase shift, is the same when passing through the bars and when passing through the filler material.
