Abstract

L'invention concerne un appareil de tomographie utilisant un rayonnement pénétrant Il comporte une source de rayonnement qui émet un faisceau en éventail dans une tranche d'un sujet et un détecteur constitué par un certain nombre d'éléments de détection qui délivrent des données d'intensité de faisceau La source et le détecteur sont montés sur un châssis animé d'un mouvement linéaire. Une unité de traitement de données traite les signaux obtenus de manière à reconstituer un tomogramme. Applications au diagnostic médical.
