Abstract
An X-ray examination device has an X-ray tube, a primary X-ray diaphragm attached to the X-ray tube and disposed close to the focus thereof, a patient support bed, and an X-ray exposure device disposed behind the patient's support bed in the radiation direction having an X-ray image carrier and a stray radiation screen. The primary X-ray diaphragm includes a first slit beam collimator for generating a fan-shaped radiation beam and the X-ray exposure device has a second slit beam collimator in the form of two displaceable diaphragm plates and an adjustment device for moving the plates relative to one another to achieve a slit opening therebetween of desired width. The examination device further includes synchronized drive units for moving the X-ray tube and the second beam collimator in fixed alignment for sweeping the radiation beam across a patient on the support bed.
