Reproduction of x-ray images with photostimulable phosphor.

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 an oxyorthosilicate corresponding to the following empirical formula (I) : Y2SiO5:Ce<3><+>, Sm<3><+> (I) wherein : Ce<3><+> is present in an atomic percentage in the range from 0.01 to 5 with respect to the yttrium concentration taken as 100 atom %, Sm<3><+> is present in an atomic percentage in the range from 0 to 5 with respect to the yttrium concentration taken as 100 atom %.
