Abstract

Appareil permettant une exploration couche par couche des tissus examinés. Il comprend des moyens tournants 25 portant des moyens d'émission de rayons X et de détection des rayons X, des moyens d'entraînement 45 accouplés aux moyens tournants pour les faire tourner, des moyens de codage 40 comportant des moyens d'accouplement avec les moyens tournants et des moyens sensibles aux moyens d'accouplement pour former un train d'impulsions de synchronisation, chaque impulsion correspondant à une position déterminée de la plage rotation des moyens tournants. Application à la radiographie des tissus mous.
