ABSTRACT:
In a short-time tomosynthesis apparatus for imaging layers of a body to be examined, the body is irradiated by radiation beams from a large number of different directions in order to form perspective images. The radiation beams are detected by a detector which is arranged underneath the body. The perspective images appearing on the exit of the detector will overlap when the radiation beams have a comparatively large angle of aperture. For separating the perspective images, an image separating system is provided at the exit of the detector. The image separating system may comprise a fiber-optical system or an electron-optical deflection unit.
