Abstract

In an x-ray diagnostic apparatus for tomosynthesis or laminographic imaging using a patient positioning table, an x-ray source which emits an x-ray beam on one side of the patient positioning table, an x-ray detector arranged on the other side of the patient positioning table for the capture of the x-ray beam and for producing digital images, a device for movement of the x-ray source, a device for shifting of the x-ray detector and a device for superimposing the digital images so that only the details lying in a specific longitudinal slice for an examination subject are sharply imaged, the x-ray detector is rotated relative to the movement direction at an angle.
