FIELD: physics.
SUBSTANCE: x-ray system (2) for obtaining the image of the object has X-ray detector (8), which is divided into a plurality of adjacent detector cells. In particular, the image may be a two-dimensional projection image, but also a 3D object volume reconstructed from the collection of tomosynthesis data. Movement mechanism (18) of the X-ray detector is adapted for moving X-ray detector (8) at least between the first position of the X-ray detector and the second position of the X-ray detector during operation of the X-ray system. X-ray source (4), collimator (22) and X-ray detector (8) of X-ray system (2) are adapted to collect a plurality of partial X-ray images by adjacent detector cells when the object is irradiated with X-ray beams at a plurality of angles α of tomography.
EFFECT: information processing unit is configured to generate a two-dimensional image of the object and / or restore the three-dimensional volume of the object from the collected partial images.
