Abstract
Mejoras introducidas en el objeto de la Patente Principal Nº 468.229, o sea en "Una disposición para la reproducción de una rebanada plana de un cuerpo con al menos una fuente de radicación gamma o de rayos X", habiendo un haz primario de pequeña sección transversal que pasa a través del cuerpo y siendo la radiación dispersa o difusa, por él producida, incidente, a través de una abertura o rendija, sobre un dispositivo de detectores que consta de una pluralidad de detectores, caracterizadas por el hecho de que , en una región comprendida entre el haz primario y el dispositivo de detectores, hay dispuestas gran número de láminas de un material que tiene un elevado factor de absorción para con la radiación, de modo que la radiación generada en el área del haz primario no es sustancialmente atenuada por las láminas, en tanto que la radiación proveniente de la región exterior al haz primario resulta fuertemente atenuada.
