Dec 20, 1999
Appl. No.:
09/467409
Inventors:
Douglas L. Vizard - Durham CT

Eastman Kodak Company - Rochester NY
International Classification:
G01T 1164
US Classification:
250367
Abstract:
An electronic imaging system including; a transparent support having first and second sides; an optical interference coating on the first side of the transparent support; and a first prompt phosphor layer overlaying the interference coating for use in high resolution ionizing radiation imaging application or in low energy ionizing radiation imaging applications. The system also includes a second prompt phosphor layer which is removably overlaid on the first prompt phosphor layer for use in high energy ionizing radiation applications; and an electronic camera for converting the light image produced by the first and the second prompt phosphor layers when exposed to an ionizing radiation image, into an electronic image; wherein the phosphor of the first and second prompt phosphor layers emits radiation at wavelengths which are passed by the optical interference coating.
