ABSTRACT:
In a method for producing a tomosynthesis exposure a reference object is used which is formed by a region of the examination subject. It is thus possible to determine the distance of the beam transmitter to the beam receiver and to the examination subject, the irradiation angle, and the direction of irradiation, on the basis of the signals that can be derived from the beam receiver during the transillumination of the reference object, without the reference object causing any disturbance in the region of the subject of examination.
