Abstract

Dispositif perfectionné de commande du collimateur et de contrôle de la position d'une cassette dans un appareil de diagnostic radiographique. Il comporte un circuit électronique et des éléments électromécaniques conçus de manière à empêcher toute exposition aux rayons X tant qu'une cassette de dimensions normalisées, placée sur un porte-cassette, n'est pas convenablement centrée et positionnée par rapport à la source de rayons X. Domaine d'application : appareils de radiographie.
