Abstract

The invention relates to an arrangement for producing X-ray images, which arrangement comprises an X-ray source (1) for the generation of an X-ray beam (10), a layer (41) sensitive to X-rays and situated on a cylindrical drum (4), and a read unit (5) for converting the X-ray image detected in the layer into electrical image values. In order to improve the X-ray images which can be produced by the arrangement an image processor (21) includes a module (212) for transforming the X-ray image (I) situated on the layer into an X-ray image (I.sub.v) situated in a virtual plane (12), and a module (211) for improving the uniformity of the modulation transfer function (MTF) over the X-ray image produced.
