Abstract

L'invention concerne un procédé de contrôle d'un film radiologique réinscriptible (2), caractérisé en ce qu'il comporte les étapes de : - Emission (E4) d'une onde ultrasonore (5) de fréquence prédéterminée de manière à ce qu'elle traverse le film à contrôler, - Réception de l'onde ultrasonore ayant traversé le film à contrôler, - Mesure (E6) d'une atténuation de l'onde ultrasonore reçue.
