Abstract

L'INVENTION CONCERNE UN INTENSIFICATEUR D'IMAGE DU TYPE A FOYER PROCHE. CET INTENSIFICATEUR COMPORTE AU MOINS UNE PHOTOCATHODE ET AU MOINS UN ECRAN ANODIQUE DISPOSES FACE A FACE DANS UNE ENVELOPPE SOUS VIDE ET ENTRE LESQUELS EST ETABLI UN CHAMP ELECTRIQUE. LA PHOTOCATHODE ET L'ECRAN ANODIQUE ONT CHACUN LA FORME D'UNE BANDE DONT LA DIRECTION LONGITUDINALE EST PARALLELE A L'AXE DE L'ENVELOPPE. L'INVENTION S'APPLIQUE NOTAMMENT A LA TOMOGRAPHIE EN RAYONS X OU EN RAYONS GAMMA.
