Abstract: A synchronisation system comprises aa sensor arrangement to detect a trigger base event. An analysis module and an arithmetic unit are configured to access prior information on a time delay between the sensor arrangement's detection of the trigger base and a starting point of an acquisition time interval for acquiring imaging data.
