Abstract

Apparatus for the layer-wise imaging of an object by means of a large number of radiation sources which are situated in a radiation source plane and whose radiation beams intersect one another so that the approximately equally large radiation beam cross-sections which are situated in one irradiation plane almost completely cover one another. A record carrier is arranged on the other side of the object in order to record perspective images produced by the radiation beams. A imaging matrix which comprises imaging elements for the superposition of the perspective images on an image display device is disposed behind the record carrier. Displacement means are provided in order to realize a relative movement between the irradiation plane and the object or an object table carrying the object.
