The invention relates to a method and an apparatus for spatially displaying a region to be examined of an examination object, which has an x-ray emitter which can be rotated about the examination object in order to generate an x-ray beams and an x-ray detector which can be rotated about the examination object in order to record a part of the x-ray beam penetrating the examination object, with a facility having an opening for fading-in a split beam being arranged at a distance from the x-ray emitter. By being able to adjust the opening and/or the distance of the fade-in facility, a method and an apparatus can be provided, with which the radiation exposure for an examination object is reduced.
