  • Method and apparatus for tomography wherein signal profiles derived from an out-fanning beam of penetrating radiation can be reconstructed into signal profiles each corresponding with a beam of parallel incident rays
    Patent number: 4168435
    Abstract: A method and apparatus for pre-processing by means of analogue techniques radiological information obtained by exposing a subject at various spaced positions on one side of this subject to an out-fanning, substantially flat beam of penetrating radiation. The resultant ray transmissions on the other side of the subject are recorded on a record medium as continuous and analogue signals located along a collection of recording paths each having a predetermined trajectory and a spatial orientation related to an associated position of exposure. The radiological information thus recorded is then scanned and read-out along another collection of adjacent scanning paths each having a predetermined trajectory which intersects different recording paths and likewise having a spatial orientation related to the associated position of exposure.

  • Apparatus for tomography
    Patent number: 4164657
    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.
