Abstract
a. Appareil de formation d'image de rayonnement. b. Il comporte un groupe fixe de sources de rayons X sous forme de diodes à cathode froide et un groupe fixe voisin de détecteurs de rayonnement. Les diodes sont pulsées successivement avec des impulsions de tension relativement basse et de durée relativement longue. Les signaux de sortie des détecteurs sont traités pour reconstituer une image d'une tranche d'un corps. c. Tomographie par calculateur.
