Abstract

The invention relates to an X-ray imaging system (100). The X-ray imaging system comprises: an X-ray source (110) for generating X-ray radiation (118) at an X-ray focal spot (116); a detector (120) comprising detector pixels (122) for detecting X-ray radiation (118) from the X-ray source (110); an anti-scatter grid (130) located between the X-ray source (110) and the detector (120), wherein the anti-scatter grid (120) comprises grid cells aligned with the detector pixels, wherein a majority of the grid cells are focused grid cells (132) that are focused towards a common focus area, wherein at least one of the grid cells is a monitoring grid cell (134), wherein the monitoring grid cell (134) is focused towards a focus area different from the common focus area; and a processing unit (140) configured to read out a detector signal from the detector pixels (122), wherein the processing unit (140) is configured to determine a change of the focal spot by analyzing detected X-ray radiation (118) transmitted through the monitoring grid cell (134).
