摘要

collimator controller, method of controlling a collimator in an x-ray imager to obtain an image of an object, x-ray imager system, computer program element for controlling an apparatus, and computer readable media controller (cc) is a related method of controlling a collimator (col). the controller (cc) operates to select a collimator setting for the collimator (col) of an x-ray imager (100) to obtain an image of a roi in a patient (pat). the controller (cc) operates to select the collimator setting to optimize the patient dose with respect to primary radiation (pr) and secondary radiation dose (sr) of medical staff (ms). a position sensor (pd) gives the controller (cc) a current position of a person (ms) relative to the patient (pat). Based on the given position provided, the controller optimization procedure (ss) takes into account the staff dose (ms) with respect to secondary radiation (sr) to reduce it. 1/1
