Abstract

Dispositif pour la fabrication de radiographies stratifiées, à l'aide d'un dispositif d'enregistrement d'images comprenant un tube intensificateur d'images et une caméra de télévision. Ce dispositif comprend un tube d'images à fonction de mémoire et une unité de correction qui diminue les déformations inhérentes au dispositif d'enregistrement. Des déformations géométriques supplémentaires se produisent en raison du fait que le plan de l'écran d'entrée du tube intensificateur est décalé d'un certain angle de rotation par rapport au plan de la couche d'enregistrement On impose alors à la trame d'image une rotation déterminée, ce qui convertit ces déformations supplémentaires en déformations que l'on sait corriger. La trame d'image est ensuite ramenée dans sa position initiale par rotation inverse le circuit selon l'invention a éliminé les déformations géométriques supplémentaires. Application aux équipements tomographiques utilisés en médecine
