Abstract

L'invention concerne un dispositif de lecture d'images par rayonnement. Une image par rayonnement enregistrée dans une substance luminescente stimulable est lue par un photodétecteur 13 en balayant la substance luminescente 11 par un rayonnement laser issu d'une source 15. De façon caractéristique un guide de lumière 12 sert à la transmission efficace de la lumière au photodétecteur 13. Application au diagnostic médical.
