Abstract
L’invention concerne un ensemble de radiologie (10) comprenant : un tube générateur (11) d’un faisceau de rayons X (12) centré autour d’une direction principale (13) d’émission, un capteur plan (14) s’étendant selon un plan défini par une première direction (D1) et par une deuxième direction (D2), sensiblement perpendiculaires à la direction principale (13) d’émission rayon X, destiné à recevoir les rayons X (12), caractérisé en ce qu’il comprend : un premier émetteur interrompu (15) en deux parties d’émetteur de champ électromagnétique ; un deuxième émetteur interrompu (16) en deux parties d’émetteur de champ électromagnétique ; un émetteur dit plan (24) de champ électromagnétique, des capteurs (29, 30, 31, 32) de champ électromagnétique solidaires du capteur plan (14), un moyen de traitement (17) destiné à déterminer un angle d’alignement entre la direction principale (13) d’émission et une normale (N1) du capteur plan (14), à déterminer une première erreur de centrage et une deuxième erreur de centrage, un moyen de correction (171) de l’angle d’alignement par application d’un premier mouvement correctif sur le tube générateur (11) et des première et deuxième erreurs de centrage par application du premier mouvement correctif et/ou d’un deuxième mouvement correctif sur le tube générateur (11).
