Binderless storage phosphor screen comprising a support including an amorphous (a-C) carbon layer

A method for exposing an object to X-rays comprising the steps of:

• providing an X-ray machine including an X-ray tube equipped for emitting X-rays with an energy lower than or equal to 70 keV and a phototimer coupled to said X-ray tube for switching said tube on and off in accordance with an X-ray dose in the range from 0.75 up to 0.85 mR reaching said phototimer,
• placing an object between said X-ray tube and said phototimer,
• placing a cassette with a binderless storage phosphor panel or screen between said object and said phototimer and
• activating said X-ray tube for exposing said object, said cassette and said phototimer until said phototimer switches said X-ray tube off, wherein said binderless storage phosphor panel comprises a vacuum deposited phosphor layer (1) on a support (2), and wherein said support includes a layer of amorphous carbon (23) having a thickness between 500 μm and 2000 μm.
