The present invention relates to a system (1) for controlling an X-ray detector (11) for detection of X-ray radiation, an X-ray imaging arrangement (3) comprising such system (1) and a method for controlling an X-ray detector (11) for detection of X-ray radiation. The system (1) for detection of X-ray radiation comprises a trigger device (12). The trigger device (12) is configured to be arranged remotely from the X-ray detector (11). The trigger device (12) is furthermore configured to be data-linked to the X-ray detector (11). The trigger device (12) is configured to determine a start of an X-ray exposure of an X-ray tube (2), to generate an activation signal and to communicate such signal the X-ray detector (11) to activate image detection.
