Recognizer for staff or patient body parts using markers to prevent or reduce unwanted radiation

摘要

An imaging system and a related method include a marker detection system (MDS) to detect one or more markers (MK) spatially arranged in association with an area (A). If the marker detection system (MDS) detects that the area (A) is within a field-of-view (FoV) of the imaging system or is at least within a predefined distance thereof, a control signal is issued in respect of the area (A) to an image acquisition system (ACS) of the imaging system. The area (A) may be one of a hand of a human operator or a part of a patient to be imaged.
