description The present invention relates to a device for controlling a position of an anti-scatter grid in an X-ray image acquisition system, the device (10) comprising: a measurement unit (12); a control unit (14); and a shifting unit (16); wherein the measurement unit (12) is configured to determine an X-ray beam focus position (37) of an X-ray radiation source of the X-ray image acquisition system with respect to an X-ray detector of the X-ray image acquisition system; wherein the control unit (14) is configured to generate a shifting signal based on a displacement (18) between the X-ray beam focus position (37) and a grid focus position (35) of the anti-scatter grid; and wherein, based on the shifting signal, the shifting unit (16) is configured to shift an anti-scatter grid of the X-ray image acquisition system in at least one direction to align the anti-scatter grid with the X-ray beam focus position (37), provides an improved anti-scatter grid for X-ray acquisition systems. The invention provides the use of an improved anti-scatter grid (26) for X-ray acquisition systems (20).
