ABSTRACT:
In a method and an apparatus for producing a tomosynthesis exposure of an examination subject, an X-ray beam is directed at the subject from different directions and a reference object composed of at least two sub-objects is disposed in the X-ray beam together with the subject. X-rays attenuated by the reference object composed of at least two sub-objects and the examination subject are received by a radiation receiver, which generates electrical signals corresponding to X-rays incident thereon, from which a tomosynthesis image is constructed.
