Claim 0:
1. An X-ray imaging system for acquiring two-dimensional or three-dimensional images of a subject, the imaging system comprising:
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 X-rays, which has been passed through the subject, wherein the X-rays are received on an X-ray sensitive surface of the detector system;
an anti-scatter arrangement, which is arranged in the beam path of the X-rays between the X-ray emitting region and the detector system;
wherein the imaging system is configured to acquire a first and a second image of the subject, wherein each of the first and second images shows
(a) a same portion of a body of the subject and
(b) an image artifact generated by the anti-scatter arrangement (9);

wherein the imaging system is configured to:
control a relative position of at least one of the one or more X-ray emitting regions, as seen in a coordinate system which is stationary 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 relative to the anti-scatter arrangement and/or the X-ray sensitive surface; and to
generate, 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 generated by the anti-scatter arrangement, are reduced, suppressed or eliminated compared to the first and the second image.
