Title
(EN) X-RAY TUBE WITH ROTATING ANODE APERTURE
(FR) TUBE À RAYONS X À OUVERTURE D'ANODE ROTATIVE
Abstract
(EN)
An x-ray tube for generating a sweeping x-ray beam. A cathode is disposed within a vacuum enclosure and emits a beam of electrons attracted toward an anode. The anode is adapted for rotation with respect to the vacuum enclosure about an axis of rotation. At least one collimator opening corotates with the anode within the vacuum enclosure, such that a swept x-ray beam is emitted.
(FR)
Cette invention concerne un tube à rayons X pour générer un faisceau de rayons X de balayage. Une cathode est disposée dans une enceinte à vide et elle émet un faisceau d'électrons attiré vers une anode. L'anode est conçue pour tourner sur un axe de rotation par rapport à l'enceinte à vide. Au moins une ouverture de collimateur tourne en synchronie avec l'anode à l'intérieur de l'enceinte à vide, de telle façon qu'un faisceau de rayons X de balayage est émis.
