Abstract: The invention relates to a device for the imaging layers of a three-dimensional object. The device comprises a group of radiation sources which are situated in a common radiation source plane in order to irradiate an object arranged on an examination table. The drive also comprises a record carrier situated underneath the object for recording a source-distribution encoded image of the object. The encoded image consists of respective perspective images. The radiation source group and the record carrier are arranged to slide in opposite directions in parallel planes relative to the stationary object during a radiographic recording. Each of the connecting lines between the radiation sources and the center of the record carrier, pass through a corresponding fixed point in the object for all positions of the radiation source group.
