Abstract

L'INVENTION S'APPLIQUE A UN APPAREIL POUR EFFECTUER UNE TOMOGRAPHIE CALCULEE A EMISSION DE POSITONS, FONCTIONNANT PAR DETECTION DE RAYONS GAMMA AU MOYEN DE DETECTEURS 121 COMPRENANT UN SCINTILLATEUR 122 ET UN PHOTOMULTIPLICATEUR 123 DE FACON A FOURNIR DES SIGNAUX DE SORTIE TRAITES PAR UN CALCULATEUR QUI RECONSTITUE UNE IMAGE DE LA COUPE TOMOGRAPHIQUE. LES DETECTEURS SONT DISPOSES EN RANGEES QUI SONT PORTEES PAR UN CHASSIS 111 TOURNANT AUTOUR DU SUJET A EXAMINER 132 ET QUI COMPRENNENT AU MOINS UN DETECTEUR EN UNE POSITION IRREGULIERE PAR RAPPORT AUX AUTRES DETECTEURS DE LA RANGEE POUR L'OBTENTION D'UNE BONNE DENSITE D'EXPLORATION, CHAQUE RANGEE OCCUPANT LA PLACE D'UNE RANGEE ADJACENTE PAR ROTATION D'UNE FRACTION DE TOUR DE L'ENSEMBLE DES RANGEES TOURNANTES.
