Abstract

Améliorations relatives à une plaque sensible aux rayons X, à un procédé de production de cette plaque, à une substance luminescente photostimulée et à un procédé de production de cette substance, comprenant (1) un moyen permettant de n'utiliser qu'une étape de calcination ou d'enlever un substrat d'une feuille de substance luminescente afin d'améliorer l'intensité de luminescence, (2) un moyen permettant d'ajouter un ou plusieurs films résistant à l'humidité sur le film de protection ordinaire, (3) un moyen permettant d'éliminer un liant contenu dans la substance luminescente par la réduction en cendres, afin d'améliorer l'intensité de luminescence, (4) un moyen permettant d'effectuer la calcination de manière à obtenir un semi-produit concassé par une plaque de quartz pour compenser un gauchissement d'une plaque sensible aux rayons X, (5) un moyen permettant d'utiliser au moins de l'hélium comme gaz réducteur dans le but de convertir entièrement l'europium tervalent contenu dans le matériau brut d'une substance luminescente en europium bivalent, de manière à améliorer l'intensité de luminescence, et (6) un moyen permettant d'utiliser un composé complexe contenant des halogénures de métaux alcalino-terreux et un sulfure d'un métal alcalino-terreux, par exemple BaCl2-xBaBr2-yCas:zEu2+ et autres pour accroître l'intensité de luminescence dans la plage de longueurs d'ondes comprises entre 650 et 850 nm, de manière à permettre l'utilisation d'un laser à semi-conducteur comme lumière d'excitation.
