Abstract
A tomosynthesis apparatus for the formation of layer images of a body. The apparatus has a large number of radiation source positions which are situated in one radiation source plane. The radiation from the sources in stopped by a diaphragm device so that the radiation beams passing through the diaphragm apertures irradiate a common superposition zone and are incident on a detector surface which is arranged behind the superposition zone. The diaphragm apertures are shaped so that in the detector plane the edge of the radiation beam of each radiation source is at least locally tangent to the edge of a cylinder which is centrally projected onto the detector surface by the radiation source and which is situated within the superposition zone. The axis of the cylinder extends at least approximately perpendicular to the radiation source plane.
