Abstract

La presente descripción describe un dispositivo detector que comprende una pluralidad de ensambles de detectores. Cada ensamble de detector comprende al menos una de las unidades de cristal de detección que tienen una primera respuesta de energía y los que tienen una segunda respuesta de energía, que están ambos dispuestos a lo largo de una primera dirección a intervalos, cada unidad de cristal de detección que tiene una primera/segunda respuesta de energía, que incluye al menos uno de los cristales de detección que tienen una primera/segunda respuesta de energía dispuesta a lo largo de una segunda dirección. La al menos una de las unidades de cristal de detección que tienen una primera respuesta de energía y la al menos una de las unidades de cristal de detección que tienen una segunda respuesta de energía, al menos parcialmente, están dispuestas alternativamente a lo largo de la primera dirección cuando se ve desde una dirección de incidencia de los rayos X. La presente descripción también describe un sistema de TC de energía dual que tiene el dispositivo detector y un método de detección de TC que usa este sistema.
