Abstract
APARATO DE TOMOGRAFIA TRANSAXIAL POR EMISION DE POSITRONES. CONSTA DE UN POLIGONO DE MATRICES DETECTORAS (1 A 6), CONSTRUIDAS COMO CAMARAS DE RAYOS GAMMA DE BARRAS CRUZADAS, QUE RODEAN A SU OBJETO A EXAMINAR, CON TUBOS DE FOTOMULTIPLICADORES (PTMIJ), UNIDADES ARITMETICAS DE INTEGRACION Y DISCRIMINACION, Y CIRCUITOS DE COINCIDENCIA EN EL TIEMPO (CCT), TODO ELLO PARA FORMAR IMAGENES DE RODAJAS DEL OBJETO. UN CONVERTIDOR ANALOGICO-DIGITAL (ECR), COMUN A TODAS LAS MATRICES, SUMINISTRA A UNA MEMORIA (M) LOS DATOS CORRESPONDIENTES A CADA FOTON DETECTADO.
