Abstract
L'invention concerne un tube à rayons X. Le tube est caractérisé en ce qu'il comporte une anode opérant par transmission, formée d'une cible mince en matériau réfractaire émettant les rayons X, déposée sur un support absorbant faiblement le rayonnement émis par la cible, un dispositif de collimation placé devant l'anode, ladite anode étant balayée, sous l'action d'un système de déviation, par le faisceau d'électrons émis par une cathode de façon à produire, en coopération avec le dispositif de collimation, un ensemble de faisceaux de rayons X fins, sensiblement parallèles et coplanaires. Application à des tomodensitomètres.
