Abstract

La presente solicitud divulga un sistema de tomografía computarizado que tiene fuentes de rayos X no giratorias que son programadas para optimizar el patrón de disparo de la fuente. En una modalidad, el sistema de CT es un escáner de CT de haz de cono rápido que utiliza un anillo fijo de múltiples fuentes y anillos fijos de detectores en una geometría desfasada. Se debe apreciar que el patrón de disparo de la fuente se efectúa por medio de un controlador, el cual implementa métodos para determinar un patrón de disparo de la fuente que se adapta a las geometrías donde la geometría de las fuentes de rayos X y el detector están desfasadas.
