Abstract
Aparato para determinar diferencias de absorción de radiación locales en un cuerpo, que comprende una fuente de radiación para generar un haz de radiación en forma de abanico que irradia al cuerpo, medios detectores que son sensibles a la posición en al menos una dirección, un mecanismo explorador, estando siempre situados la fuente de radiación y los medios detectores uno frente a otro, uno a cada lado de un eje central que pasa por el cuerpo a examinar, y medios para ajustar la distancia entre un eje central que pasa por el cuerpo a examinar y la fuente de radiación y/o los medios detectores para adaptar la anchura del haz en la región ocupada por el cuerpo a una dimensión pertinente del cuerpo.
