X-ray system, rotary unit and methods

An X-ray system comprises a radiation source, a radiation detector; and, disposed between the radiation source and the radiation detector rotation unit. This has at least two receiving devices for at least two objects and is adapted individually to each to rotate the at least two objects own axis of rotation. Further, the X-ray system comprises a calculation unit which is configured on radiating through the at least two objects by means of the radiation source and the radiation detector based on radiographic data, determined by means of the radiation detector to calculate a reconstruction data set for each object of the at least two objects.
