An X-ray diagnostic apparatus for the production of panorama slice exposures of body parts of a patient, has a rotating unit with a source of radiation and, arranged diametrically thereto, a detector camera with a radiation-sensitive CCD detector and an image-processing unit with a computer, as well as a reproduction unit. For the subsequent determination of a sharp slice and/or of the depth of field, the CCD detector is formed by a number of narrow TDI zones with clock-out columns. The image signals corresponding to the image information containing charge packets are read out from the respective individual TDI zones, and are subject to calculations in the image processing unit, so that the depth of field of a selected slice position can be determined by modifying the local displacement of the individual images using an input unit that interacts with the image processing unit.
