Abstract

L'invention porte sur un système de photographie par rayons X permettant d'exécuter des photographies stables en connaissant avec précision le temps d'irradiation par les rayons X, même si le générateur de rayons X n'est par remodelé et se trouve en mode de veille où la consommation de la batterie est réduite. Le système de photographie par rayons X comporte: une unité de détection (42) du courant fourni au générateur de rayons X en appliquant un faisceau d'électrons à une anode tournante reliée à la ligne d'alimentation électrique extérieure du générateur, et un moyen de commande (1) commutant un détecteur d'images par rayons X (6) du mode de veille au mode photographie, et faisant passer le détecteur d'images d'un état de sortie de charge à un état de stockage de charge en fonction de la valeur de l'unité de détection du courant (42) accompagnant le début de la rotation de l'anode tournante, et (2) faisant passer le détecteur d'images à l'état de lecture de charge en fonction de la valeur de l'unité de détection de courant (42) accompagnant l'arrêt de l'irradiation par le générateur de rayons X (3).
