Abstract

Un detector de rayos X, que comprende un elemento de detección de rayos X y un dispositivo de detección que es sensible a la radiación fluorescente generada en el elemento de detección de rayos X, caracterizado porque el elemento de detección de rayos X contiene un material fluorescente que posee una luminiscencia residual corta así como también una alta sensibilidad para la radiación X que ha de ser detectada.
