Abstract
Analog method and apparatus for producing an axial tomographic image of an object, typically the human body, using a detector for receiving radiation along a plurality of sets of paths, with the sets of paths overlapping each other, and providing a plurality of sets of detector output signals. Prior art devices exist for producing the detector output signals, which signals are then manipulated in a digital computer to produce the desired image. In one embodiment of the present invention, the detector output signals are summed in a storage tube and the stored signals are read in an inversely proportional relation, providing another signal for storage in another storage tube which is then read with a Laplacian relation to give a video signal for display and/or recording. Optical and electrostatic storage systems are also disclosed.
