Abstract

El explorador de tomografía computarizada (40) incluye una fuente de rayos X (42) y un conjunto de detectores de rayos X (44) fijado a un disco de geometría reducida (46) que se soporta para girar alrededor de un isocentro (48) del disco. La fuente de rayos X es una fuente de potencia reducida, y se coloca un filtro endurecedor del haz (45) de un tamaño reducido, proximal a la fuente de rayos X, de tal manera que el explorador utiliza un haz de rayos X relativamente suaves. El explorador incluye además circuitos para compensar las no linearidades y la variacion de canal a canal en los detectores de rayos X. La figura más representativa de la invencion es la numero 1.
