Publication number: 20240324971Abstract: 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. The starting point is computed of the acquisition time interval from the detected trigger base event and the prior information of the time delay. The time delay between the sensor arrangement's detection of the trigger base event and the acquisition time interval may vary between individual subjects, but for each individual subject the time delay is well reproducible and hence on a per subject basis may be calibrated for.Type: ApplicationFiled: July 11, 2022Publication date: October 3, 2024Inventors: Steffen Weiss, Wenjin Wang, Albertus Cornelis Den Brinker, Albert Garcia Tormo
