Electronic imaging screen with optical interference coating

An electronic imaging system comprising;

• a transparent support having first and second sides;
• an optical interference coating on said first side of said transparent support;
• a first prompt phosphor layer overlaying said interference coating for use in high resolution ionizing radiation imaging application or in low energy ionizing radiation imaging applications;
• a second prompt phosphor layer which is movable between a first position overlaying said first prompt phosphor layer for use in high energy ionizing radiation applications and a second position removed from said first prompt phosphor layer;
• and
• an electronic camera for converting the light image produced by said first and said second prompt phosphor layers when exposed to an ionizing radiation image, into an electronic image;
• wherein said phosphor of said first and second prompt phosphor layers emits radiation at wavelengths which are passed by said optical interference coating.
