Abstract

L'invention concerne la tomographie. dans lequel le Il est décrit un appareil de tomographie dans lequel le rayonnement X est dirigé à travers un passage qui contient un élement de collimation pour réduire le rayonnement transmis perpendiculairement à une direction moyenne d'émission. Cet elément de collimation est constitué d'une première et une deuxième plaques collimatrices superposées et espacé d'une largeur égale à l'épaisseur d'une tranche de corps examiné, avec en outre une troisième plaque collimatrice entre les premières. Application aux appareils de diagnostic médical.
