Abstract

A method is for operating an X-ray device. In an embodiment, the method includes acquiring a sequence of images of a patient; moving an acquisition arrangement including at least one X-ray tube assembly, during the acquiring of the sequence of images, along the patient in a scanning direction; evaluating at least two different images, showing at least one common feature of the patient, to determine depth information for the at least one common feature; and actuating a collimator aperture of a collimator of the X-ray tube assembly, as a function of position information describing a position of the acquisition arrangement in the scanning direction, to change an aperture angle of a radiation field generated by the X-ray tube assembly in the scanning direction.
