Publication number: 20260195859Abstract: System (SYS) and related method for acquisition lag correction in X-ray imaging. The system comprises an input interface (IN) for receiving input including an input image acquired by a front layer detector (FLD) in a multi-energy X-ray imaging apparatus (IA). A corrector component (CC) processes the input image into a corrected version that represents an estimate for image information at lower acquisition lag than the acquisition lag experienced for the input image. Specifically, effects of lag and associated artifacts are removed, and the corrected version is an estimate for the input image in an acquisition setup where there was no such acquisition lag.Type: ApplicationFiled: November 30, 2023Publication date: July 9, 2026Inventors: Dirk SCHÄFER, Nikolas David SCHNELLBÄCHER, Walter RUETTEN, Matthias SIMON

Patent number: 11219425Abstract: The invention relates to off-center detector X-ray tomography reconstruction of an image of an object on the basis of projection data acquired during a rotation of an X-ray source and the off-center detector around the object in two rotational passes of less than 360°, wherein a focus point of the X-ray beam travels along largely overlapping arcs (401, 402) in the two rotational passes, the off-center detector being positioned asymmetrically with respect to a central of the X-ray beam and a direction of a detector offset being reversed between the passes. According to the invention, redundancy weighting of the projection data with respect to a redundant acquisition of projection values during each of the rotational passes is made using a redundancy weighting function determined on the basis of a union of the arcs (401, 402).Type: GrantFiled: December 19, 2017Date of Patent: January 11, 2022Assignees: KONINKLIJKE PHILIPS N.V., ION BEAM APPLICATIONS S.A.Inventor: Dirk Schäfer
