Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Ermittlung der Qualität einer Speicherfolie, mit dem Schritten eines Durchführens einer Belichtung der Speicherfolie, eines Durchführens eines Scans der Speicherfolie zur Ermittlung eines Bildes, eines Ermittelns eines Signal-zu- Rauschen-Verhältnisses des Bildes oder/und eines Durchführens einer Kantenerkennung an dem Bild und einem Berechnen eines Qualitätswertes der Speicherfolie auf Basis des Signal-zu-Rauschen-Verhältnisses des Bildes oder/und auf Basis der erkannten Kantenstruktur. Des Weiteren betrifft die Erfindung einen Speicherfolien-Scanner zur Durchführung eines solchen Verfahrens.
(EN)
The invention relates to a method for determining the quality of an imaging plate, comprising the steps of carrying out an exposure of the imaging plate, carrying out a scan of the imaging plate in order to determine an image, determining a signal-to-noise ratio of the image or/and carrying out edge recognition on the image and calculating a quality value of the imaging plate on the basis of the signal-to-noise ratio of the image or/and on the basis of the recognized edge structure. Furthermore, the invention relates to an imaging plate scanner for carrying out such a method.
(FR)
L'invention concerne un procédé pour déterminer la qualité d'un écran à mémoire, comprenant les étapes consistant : à effectuer un éclairage de l'écran à mémoire, à effectuer un balayage de l'écran à mémoire pour déterminer une image, à déterminer un rapport signal/bruit de l'image et/ou à effectuer une détection de contours sur l'image et à calculer une valeur de la qualité de l'écran à mémoire en fonction du rapport signal/bruit de l'image et/ou en fonction de la structure de contours identifiée. Cette invention concerne en outre un scanner pour écran à mémoire servant à la mise en œuvre de ce procédé.
