Radiation image read-out apparatus

摘要

A radiation image read-out apparatus includes a stimulating light beam source, and a photodetector which receives stimulated emission emitted upon exposure to the stimulating light beam from portions of the stimulable phosphor sheet exposed to the stimulating light beam or the back side of the sheet opposed to the portions exposed to the stimulating light beam and converts the amount of stimulated emission to an electric signal. The photodetector comprises a CCD provided with a protective member which is permeable to light in the wavelength band of the stimulated emission and impermeable to light in the wavelength band of the stimulating light.
