Abstract

Un método perfeccionado de examen médico por medición de absorción de radiación, en donde en un campo de análisis que se hace coincidir sucesivamente con una pluralidad de ¿rebanadas¿ o láminas de cuerpo paralelas del cuerpo a ser examinado se definen cada vez una pluralidad de zonas elementales en el plano de intersección de cada vez, una pluralidad de líneas de análisis que se cortan situadas en el campo de análisis, mientras que para el cálculo de la absorción en una zona elemental la absorción medida a lo largo de cada una de las líneas de análisis que se cortan en la mencionada zona elemental es tratada matemáticamente merced a medios de medida que pueden ser orientados y que comprenden los siguientes componentes a cualquiera de los lados del campo de análisis y en el plano del mismo: una fuente de radiación y un sistema de n detectores de medida de centelleo o escintilación alineados, *** Ver imagen 01
