Abstract
Un dispositivo para determinar la distribución de la absorción de un cuerpo mediante una fuente de radiación, principalmente puntiforme, para generar una radiación que atraviese o penetre en el cuerpo, y un dispositivo detector para medir la radiación que haya pasado a través del cuerpo y para generar una señal de detector, y un dispositivo de tratamiento para derivar de las señales de detector unas señales eléctricas representativas de la absorción del cuerpo a lo largo de los haces de radiación próximos o vecinos.
