Abstract

UN METODO DE FABRICAR UN TUBO INTENSIFICADOR DE IMAGENES DE RAYOS X. EN UN TUBO INTENSIFICADOR DE RAYOS X (1) SE FORMA UNAPANTALLA DE ENTRADA (8) DEPOSITANDO MATERIAL LUMINISCENTE (22) EN UN ANGULO DE 0 CON UNA NORMAL A LA PANTALLA. LA ESTRUCTURA DE LA PANTALLA PUEDE HACERSE ASI OPTIMA CON RESPECTO A LA CONDUCCION OPTICA DE LA LUZ LUMINISCENTE. POR TANTO, SE OBTIENE UN TUBO INTENSIFICADOR DE IMAGENES DE RAYOS X EN QUE CON UNA ALTA RESOLUCION Y UNA ALTA ABSORCION DE RAYOS X SE REDUCE CONSIDERABLEMENTE LA DOSIS A UN PACIENTE.
