ABSTRACT:
A method of storing an image produced by x-ray exposure and releasing the stored image is disclosed. It is disclosed to expose an x-ray storage screen, comprised of an isotropic storage phosphor and a polymer coated on a support, to x-radiation of a first wavelength in an imagewise manner to store an image pattern in the storage screen. The image pattern is retrieved from the storage screen by exposing the storage screen to radiation of a second wavelength, thereby stimulating radiation of a third wavelength. The polymer has an index of refraction which matches the index of refraction of the phosphor at the second wavelength, and the support is non-reflective to radiation of the second wavelength.
