Patent number: 11864932Abstract: The disclosure relates to an X-ray imaging system for acquiring two-dimensional or three-dimensional images of a subject. A relative position of an X-ray emitting region, as seen in a coordinate system which is stationary relative to an anti-scatter arrangement and/or an X-ray sensitive surface is controlled so that a first and a second image are acquired at different relative positions of the X-ray emitting region relative to the anti-scatter arrangement and/or the X-ray sensitive surface (10). A data processing system of the imaging system generates an output image, based on each of the images. In the output image, artefacts generated by the anti-scatter arrangement, are reduced, suppressed or eliminated compared to the first and the second image.Type: GrantFiled: December 8, 2021Date of Patent: January 9, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Nishant Singh, Klaus Jürgen Engel, Johannes Wilhelmus Maria Jacobs, Bernd Menser, Lester Donald Miller, Fred Simon Berend Van Nijnatten
