Claim 14:
15. A method for operating an X-ray imaging system for acquiring two-dimensional or three-dimensional images of a subject and for reducing artefacts which are generated by an anti-scatter arrangement of the X-ray imaging system;
wherein the X-ray imaging system comprises:
an X-ray source configured to emit X-rays from one or more X-ray emitting regions;
a detector system configured to receive a portion of the emitted X-rays, which have been passed through the subject on an X-ray sensitive surface of the detector system;

wherein the anti-scatter arrangement is arranged in the beam path of the X-rays between the subject and the detector system;
wherein the method comprises:
acquiring a first and a second image of the subject so that each of the first and second images shows at least a same portion of a body of the subject and (b) an artifact generated by the anti-scatter arrangement;
controlling a relative position of at least one of the X-ray emitting regions relative to the anti-scatter arrangement and/or the X-ray sensitive surface so that the first and second images are acquired at different relative positions of the at least one X-ray emitting region; and
generating, using a data processing system of the imaging system, an output image, based on each of the first and second images;
wherein the output image shows the portion of the body and in the output image, artefacts which are generated by the anti-scatter arrangement, are reduced, suppressed or eliminated compared to the first and the second image.
