Abstract
A radiation image recorded in a stimulable phosphor sheet or plate is visualized by stimulating the phosphor with stimulating rays. Being stimulated by the stimulating rays, the phosphor emits detectable light. The emitted light is detected by a photodetector. The wavelength of the stimulating rays is selected within the range of 600 to 700 nm. The wavelength of the light detected by the photodetector is selected within the range of 300 to 500 nm.
Claims4
A method of reading out a radiation image stored in a stimulable phosphor member comprising the steps of stimulating the phosphor stored with the radiation image with stimulating rays to cause the phosphor to emit detectable light, and detecting the emitted light with a photodetector characterized in that the wavelength of said stimulating rays is within the range of 600 to 700 nm, and that the wavelength of said light detected by the photodetector is within the range of 300 to 500 nm.
An apparatus for reading out a radiation image stored in a stimulable phosphor member comprising a stimulating ray source for generating stimulating rays to which the stimulable phosphor stored with a radiation image is exposed, and a detecting means for detecting the light emitted from the stimulable phosphor stimulated by said stimulating rays characterized in that the wavelength of said stimulating rays generated by the stimulating ray source is within the range of 600 to 700 nm, and that said detecting means detects the light having a wavelength within the range of 300 to 500 nm.
