Abstract
SE REALIZA GAMMA CAMARA UTILIZABLE PARA MEDIR EL COEFICIENTE DE ATENUACION DE LA RADIACION GAMMA EN UN CUERPO ESTUDIADO A PARTIR DE UNA GAMMA CAMARA, NORMALMENTE REALIZADA PARA ESTUDIAR LOS EFECTOS DE LAS RADIACIONES GAMMAS EMITIDAS POR MARCADORES INYECTADOS EN EL CUERPO. CON ESTE PROPOSITO, SE QUITA EL COLIMADOR (18) DE ESTA GAMMA CAMARA Y SE LA SUSTITUYE POR UNA CORONA (17) Y POR UN BRAZO (13) AL CUAL ESTA FIJADO UN RECINTO (12) DESTINADO A CONTENER UNA FUENTE RADIACTIVA (11) PUNTUAL EN EXTERIOR DEL CUERPO. SE MUESTRA QUE SE PUEDEN OBTENER ASI IMAGENES TRANSMITIDAS MUY RAPIDAMENTE. ESTAS IMAGENES SON UTILES EN LA CORRECCION DE LAS IMAGENES DE EMISION NORMALES.
