Abstract

Un sistema incluye una fuente que gira alrededor de una región de examinación y emite radiación que atraviesa la región de examinación, una disposición de detector sensible a radiación que detecta radiación que atraviesa la región de examinación y genera datos de proyección indicativos de la radiación detectada, y un eliminador de ruido de datos de proyección que elimina ruido de los datos de proyección, en donde el eliminador de ruido elimina ruido de una proyección con base en un número de fotones detectados para la proyección.
