Abstract
A slit radiography device scans a body under examination with a fan-shaped x-ray beam. A number of absorption elements placed next to each other can be moved into the x-ray beam to a greater or lesser extent in order to influence the x-ray radiation incident on the body per sector of the beam. As seen in the longitudinal direction of the slit the absorption elements are designed such that a certain distance is present between them. As seen in the direction of the radiation beam the thickness of the material of the absorption elements is always the same so that there are no gaps between the elements that the x rays can shine through.
