Abstract:
A radiation image recording and reproducing method comprising the steps of:A) exposing a storage phosphor in a radiographic image storage assembly to reflected or transmitted radiation of a first wavelength to store said radiation within said storage phosphor, said radiographic image storage assembly comprising a metal screen that is positioned adjacent to a storage phosphor screen comprising said storage phosphor, said metal screen having a thickness of from about 0.1 to 0.75 mm when composed of copper or a thickness of from about 0.05 to 0.40 mm when composed of lead, and said radiographic image storage assembly positioned in relation to said exposing radiation of said first wavelength such that said exposing radiation passes through said metal screen before said storage phosphor screen, B) exposing said storage phosphor to radiation of a second wavelength to release said stored radiation as light emission of a third wavelength, the second wavelength radiation being directed through said metal screen before it reaches said storage phosphor, and C) detecting said emitted light of said third wavelength.
