Abstract
An X-ray intensifying screen pair comprising a thin screen and a fiber optic thick screen is disclosed, together with a method for producing the fiber optic thick screen, which method includes the steps of evaporation and vacuum deposition. The thin screen comprises a gadolinium oxysulphide rare earth scintillator capable of providing good image resolution, and the fiber optic thick screen comprises a thallium doped cesium iodide scintillator that is capable of high speed (i.e., good X-ray photon-stopping and photon-conversion) operation, that is stable under ambient conditions, and that requires low patient dosage.
