Abstract: An apparatus and method for removing stored energy from a storage phosphor screen in which a radiation image was recorded and then read by collecting stimulated emission from the phosphor sheet. The method is accomplished by directing onto the storage phosphor sheet an erasing light having substantially no light of a wavelength of shorter than 410 nm. The apparatus of an erasing light is provided by coating a light source with a yellow dye.

Abstract: There is described an image inputting apparatus for inputting a radiation image that is formed on a radiation sensitive panel by projecting radial rays penetrated through a subject. The apparatus includes a detector to detect the radiation image projected onto the radiation sensitive panel and a sensitivity compensating section to automatically find a sensitivity compensation value, which is employed for compensating for a sensitivity of the detector so that a signal value of the radiation image detected by the detector is substantially equal to a predetermined ideal value when a predetermined dose of the radial rays is irradiated onto the radiation sensitive panel. The apparatus also includes a storage section to store the predetermined ideal value of the signal value. The sensitivity compensating section finds an optimum sensitivity-offset value, which makes the signal value of the radiation image equal to the predetermined ideal value stored in the storage section.
