Abstract

Detector de rayos gamma con codificación de profundidad de interacción. La presente invención describe un diseño de detector de rayos gamma caracterizado porque sus elementos estructurales son los siguientes: un cristal centellador continuo, un fotodetector sensible a posición y una electrónica asociada que permite calcular, además de la energía del rayo gamma y la posición de su interacción en el cristal, la profundidad de interacción en el mismo a partir de la desviación estándar de la distribución de luz de centelleo. Dicha información se puede obtener electrónicamente, de forma analógica, y por lo tanto instantánea, a partir de los primeros tres momentos de la distribución de luz de centelleo. Además, se describe una forma de implementar dicha electrónica, mediante una red de resistencias caracterizada por computar analógicamente y de forma simultánea el 1º y el 2° momento de la distribución.
