Abstract

L'INVENTION CONCERNE UN APPAREIL D'ANALYSE A COLLIMATEURS FOCALISES. ELLE SE RAPPORTE A UN APPAREIL DE TOMOGRAPHIE GAMMA QUI COMPORTE UN PORTIQUE QUI CONTIENT DES ENSEMBLES DETECTEURS I A XII AYANT DES COLLIMATEURS TRES FOCALISES. LES GROUPES DE COLLIMATEURS ALTERNES SE DEPLACENT EN SENS INVERSES PENDANT LE BALAYAGE ET PERMETTENT L'OBTENTION D'IMAGES TRES NETTES AVEC UNE BONNE SENSIBILITE ET EN UN TEMPS COURT. APPLICATION A L'ETUDE DU CERVEAU PAR GAMMAGRAPHIE.
