ABSTRACT:
An apparatus for tomography, comprising an X-ray or gamma-ray source, at least one detector, and an image reconstruction apparatus. The detector is a spatially two-dimensional, continuous detector large enough to form a complete picture of the projection of the object section thereon, taking into consideration the place of the object section and of the source of radiation relative to the detector. The detector is connected by optical or fibre-optical means to a luminance intensifier tube. This tube may be coupled, either optically or fibre-optically, to a television pick-up tube whose output is coupled to the image reconstruction apparatus. In one form of the invention the detector is an X-ray screen, which is preferably concave towards the source of radiation.
