Radiation image read-out apparatus

摘要

A radiation image read-out apparatus comprises a stimulating ray source for emitting stimulating rays to a stimulable phosphor sheet carrying a radiation image stored therein, a photodetector comprising a photoelectric conversion device, a wavelength converting phosphor positioned between the photodetector and the stimulable phosphor sheet, and a read-out device for detecting the output of the photodetector. The wavelength converting phosphor emits fluorescent light mainly of a wavelength distribution within a sensitive wavelength range of the photodetector upon reception of light emitted by the stimulable phosphor sheet when it is exposed to stimulating rays.
