Abstract : An intraoral fluoroscopy system has been designed and developed under U.S. Army sponsorship. The system provides real-time and instant replay x-ray images at a radiation exposure on the order of 500 times less than that required for exposure of a dental x-ray film. Radiation reduction is accomplished by use of an electronic image intensifier and a video disk recorder with stop action capability, while the intraoral application is made possible by use of a coherent curved fiber optic bundle with a phosphor on its input face. The system is portable. U.S. Patent No. 3,622,785 for this system was issued in November, 1971. (Author)
