Method for recording and reproducing a pattern of penetrating radiation.

摘要

A combination is provided comprising (i) a supported or self supporting photostimulable phosphor panel (1), comprising a photostimulable phosphor layer, said phosphor being capable of storing energy upon irradiation with X-rays and of releasing said stored energy as stimulated emission light upon irradiation with stimulating light and (ii) collecting means (5) for stimulated emission light, showing a restricted angular aperture characterised in that (i) said combination further comprises a volume reflection hologram H1 (8), situated between said phosphor panel and said light collecting means and (ii) said volume reflection hologram H1 reflects stimulated emission light entering said volume reflection hologram under any angle outside a restricted angle, determined by the angular aperture of the collecting means and transmits stimulated emission light entering said volume reflection hologram under said predetermined restricted angle.
