Abstract

La tension anodique et/ou la tension de filament du tube à rayons X sont formées au moyen de deux étages en cascade H1 , H2 . Des signaux de sortie s1 , s 2 de ces étages, on tire, au moyen de circuits de rétroaction F 1 , F2 , des signaux de rétroaction f1 , f2 qui sont respectivement associés à des moyens de comparaison C1 , C2 , d'une manière telle que f1 est envoyé dans C1 , dont le signal de différence (e) commande H1 .f1 est comparé au signal de sortie de C2 , lequel est proportionnel à la différence entre le signal r d'un étage de référence R et f2 . Le circuit H2 , F2 peut être découplé à l'aide d'un commutateur K qui commute le signal r' d'un étage de référence R' pour qu'il devienne le signal de référence de C1 . Radiographies de diagnostic médical.
