Abstract

Un método de estimación de distancias en el colon de un sujeto al que se le administra por vía oral una cápsula de formación de imágenes y un agente de contraste radioopaco de manera que el colon se llena con el agente de contraste radioopaco que tiene una concentración del agente de contraste que varía en diferentes localizaciones 5 a lo largo del colon, que comprende: la emisión de radiación desde la cápsula de formación de imágenes en una localización del colon; la detección de fotones que retornan de una interacción de la radiación con una pared interna del colon y los contenidos del colon; el cálculo de la suma de dichos fotones detectados con energías correspondientes a interacciones de fluorescencia de rayos X para formar un primer recuento; el cálculo de la suma de dichos fotones detectados con energías correspondientes a interacciones de retrodispersión Compton para formar un segundo recuento; la determinación de la distancia desde la cápsula de formación de imágenes a la pared interna del colon y la concentración del agente de contraste en la localización de la cápsula de formación de imágenes en el colon utilizando los valores del primer recuento y del segundo recuento; caracterizado por que adicionalmente comprende las siguientes etapas: la repetición de la determinación de la distancia para otros puntos de la circunferencia de la pared interna del colon en la misma localización en el colon; la identificación de un pólipo a partir de las distancias determinadas; el cálculo de un ángulo que engloba el pólipo; la determinación de la anchura del pólipo a partir del ángulo calculado y las distancia determinadas.
