Abstract

L'invention concerne un système d’imagerie radiographique où l’ordre d’émission des données d’images numériques multiples mémorisées dans un détecteur d’images radiographiques peut être modifié à volonté par un opérateur exploitant la console. Le système (1) d’imagerie radiographique est muni d’une console (7) qui coordonne des informations enregistrées sur l’ordre d’imagerie avec des données d’images numériques, et d’un détecteur (2) d’images radiographiques qui crée des données d’images numériques sur la base des informations d’ordre d’imagerie émises depuis la console (7) et qui est muni d’un moyen (26) de commande servant à commander l’émission des données d’images numériques vers la console (7). La console (7) associe des commandes d’émission spécifiant l’ordre d’émission des données d’images numériques à des informations d’ordre d’imagerie et les émet vers le détecteur (2) d’images radiographiques spécifié. Le moyen (26) de commande du détecteur (2) d’images radiographiques émet les données d’images numériques vers la console (7) en fonction des commandes d’émission associées aux informations d’ordre d’imagerie indépendamment de l’ordre d’imagerie.
