1. An X-ray diagnostic apparatus for generating a tomosynthesis recording, comprising:

  • a radiation transmitter that transilluminates an object under examination from a plurality of different directions;

    a radiation receiver that is adjustably mounted relative to said radiation transmitter and that produces radiation signals for generating the tomosynthesis recording of the object under examination;

    an image-generating device that receives the radiation signals for each of the plurality of different directions and computes the tomosynthesis recording of the object under examination;

    at least one position detector that produces position signals in accordance with a positional relationship between at least any two of (i) said radiation transmitter, (ii) said radiation receiver, and (iii) the object under examination, wherein said position detector is mounted on at least any one of said radiation transmitter, said radiation receiver, or the object under examination; and

    an evaluation device that (i) evaluates the position signals to determine a deviation between the positional relationship and a desired relationship, (ii) generates correction signals in accordance with the evaluated deviation, and (iii) outputs the correction signals to said image-generating device.
