摘要: A method for recording and reproducing an X-ray image is provided which method comprises the steps of:(1) causing a photostimulable phosphor to absorb image-wise or pattern-wise modulated X-rays,(2) photostimulating said phosphor with stimulating electromagnetic radiation selected from visible light and infrared light to release from the phosphor in accordance with the absorbed X-rays electromagnetic radiation different in wavelength characteristic from the radiation used in the photo-stimulation, and(3) detecting said light emitted by photostimulation, wherein said phosphor is a haloborate.
