Abstract
The invention relates to a method (62, 64) for creating x-ray images as well as to an x-ray system. During the creation of an x-ray image, a slit diaphragm (16) is moved in front of an object (24) to be x-rayed, along a path extending between a radiation source (10) and said object (24), in order for the object (24) to be scanned. X-rays emitted by the radiation source (10) are detected by a detector (20) upon penetration of the slit diaphragm (16) and the object (24) to be x-rayed. In order to create an x-ray image using a simplified slot scanning technique, the x-ray image is created without the need for a second slit diaphragm (16) between the object (24) to be x-rayed and the detector (20), and only the radiation of which the intensity (60), detected by the detector (20) during the scan, exceeds a predefined threshold value is processed.
