Abstract
An x-ray apparatus has an exposure unit with an x-ray radiator and a diaphragm in front thereof, and a camera system with which an adjustment image is acquired of a subject positioned in front of an x-ray exposure plane. Using the adjustment image, a region to be examined of the subject is identified and an area of the x-ray exposure plane is selected such that the projection of the region to be examined of the subject is substantially inscribed in the projection of the areal section. The diaphragm is adjusted such that the x-ray radiation generated by the x-ray radiator is incident on the x-ray exposure plane only within the selected areal section.
