Abstract
In a method and a device for generating a digital tomosynthetic 3D X-ray image of an examined object, a number of individual images are made of the examined object at different projection angles relative to the normal of the patient examination table by moving the X-ray tube. In a starting position, the X-ray tube is operated with a dose that is lower than that used for subsequent individual images. At least one preliminary image is recorded at the starting position, which is then evaluated to determine the radiographic parameters required for the recording of the subsequent individual images.
