ABSTRACT:
A radiographic camera is provided having a scintillator and a plurality of photodetectors positioned to face the scintillator for providing position electrical signals. The photodetectors are disposed at different, progressively increasing, predetermined distances from a reference point to a distal point adjacent the outer periphery of a nominal field of view of the camera. The position electrical signal provided by each one of the plurality of photodetectors has an amplitude related to the distance between such one of the photodetectors and the point of impingement of radiation on the scintillator. Circuitry, responsive to a plurality of the position electrical signals, is provided for producing an extrapolated correction electrical signal, such correction electrical signal having an amplitude representative of the distance between the point of an impingement of radiation on the scintillator and a point beyond the distal point and outside of the nominal field of view of the camera. Additional circuitry, responsive to the position electrical signals and the correction electrical signal is provided for producing a pair of electrical signals representing the location of the impingement of the radiation on the scintillator relative to a reference point. With such arrangement, the nominal field of view of the camera is extended.
