Abstract

Un dispositivo para medir absorción de radiación en un objeto tridimensional, que comprende al menos un dispositivo detector bidimensional que cubre un haz de radiación de una fuente de radiación y que está dispuesto a un lado frente al objeto, midiendo dicho dispositivo detector series de valores de intensidad local del haz de radiación que ha pasado a través del objeto, siendo irradiado el objeto desde un gran número de posiciones de una fuente de radiación que están situadas en un primer plano, y comprendiendo también un dispositivo aritmético para determinar una distribución de absorción en una región irradiada del objeto, caracterizado porque el dispositivo detector está limitado, en una dirección perpendicular al primer plano, a un primer lado por el primer plano y del otro lado por un segundo plano que está situado a una distancia del primer plano y se extiende paralelamente al mismo, siendo irradiado adicionalmente el objeto desde un gran número de posiciones que están situadas en el segundo plano.
