ABSTRACT:
A novel apparatus for radiographic examination purposes comprises an x-ray source emitting a flat beam. Detectors are arranged in the plane of the beam in order each to pick up part of the beam. To avoid the Compton effect, each detector is associated with it an auxiliary detector which only receives the rays emitted by the Compton effect. An electrical circuit forms a predetermined linear combination of the signals respectively picked up by each detector and the associated auxiliary detector, this in order to prevent the errors which are due to the Compton effect when the beam passes through the body being analysed.
