Abstract : This patent discloses a high energy fluoroscopic screen for converting photons into light. A high-Z foil converts a portion of the photon flux field from a specimen irradiated by photons into secondary radiations which cause a phosphor layer to luminesce. A polycellular image converter (PIC) gathers the light emitted by the phosphor as well as converting additional photons to light. The light is sensed by a low light level TV chain. (Author)
