Abstract:
A method for removing stored energy from a storage phosphor screen comprising the steps of:(a) placing the storage phosphor screen near a first source of electromagnetic radiation which outputs a wavelength or wavelengths of about 577 nanometers to about 597 nanometers;(b) exposing the storage phosphor screen to the electromagnetic radiation emitted from the first source while preventing ultraviolet light from reaching the storage phosphor screen, wherein the source of the electromagnetic radiation used in steps (a) and (b) is selected from the group consisting of a yellow light emitting diode, a yellow laser and a low-pressure sodium vapor lamp;(c) placing the storage phosphor screen near a second source of electromagnetic radiation which outputs a wavelength or wavelengths including at least one of infrared and near-infrared; and(d) exposing the storage phosphor screen to electromagnetic radiation emitted from the second source.
