Radiography apparatus
Patent
·
OSTI ID:5414680
Radiography apparatus including radiation generating means, collimator means interposed between the radiation generating means and an object to be exposed to radiation, scintillator means disposed on the opposite side of the object from the radiation generating means for converting the radiation to light, a self-scanning, integrated array of photodiodes for receiving light and emitting responsive electrical signals, optical coupling means connecting the scintillator means to the self-scanning, integrated photodiode array and signal receiving means for storing, processing or displaying the electrical signals. Additional collimators may be employed if desired. In a nuclear isotope embodiment, collimator means are provided between the object and the scintillator means. The self-scanning array of photodiodes has one or more integrated circuit elements, each having a plurality of photodiodes, a storage capacitor on which to integrate electric charges and a multiplex switch for periodic readout by means of an integrated shift register scanning circuit.
