Abstract

APARATO DE RAYOS X PARA DETERMINAR LA DISTRIBUCION DE ABSORCION EN UNA ZONA PLANA DE EXAMEN DENTRO DE UN CUERPO. EL CONJUNTO, MONTADO SOBRE UN SOPORTE ANULAR (8), QUE PUEDE GIRAR SOBRE UN BASTIDOR (9), SE COMPONE DE UN TUBO DE RAYOS X (5), QUE SE USA PULSATORIAMENTE Y ES MOVIL, PARA EMITIR UN HAZ EN FORMA DE ABANICO, AJUSTADO POR UN DIAFRAGMA (66), QUE BARRE UNA ZONA DE POSICIONAMIENTO 81), EN LA QUE SE PUEDE INTERPONER, ALTERNATIVAMENTE, UN ABSORBENTE (10). DOS ABSORBENTES (111, 112) DELIMITAN LA LLAMADA ZONA DE EXAMEN (15). EL CONJUNTO DE RAYOS QUE ATRAVIESAN EL CUERPO QUE SE ESTUDIA (3) SE RECOGE Y ANALIZA EN EL DISPOSITIVO DETECTOR (6).
