Abstract

SE PRESENTA UN METODO Y UN CIRCUITO PARA EVITAR LA PRODUCCION EXCESIVA DE RAYOS X EN UN CRT MEDIANTE LA MEDICION CONTINUA DE LOS PARAMETROS DE FUNCIONAMIENTO DEL CRT QUE ESTAN RELACIONADOS CON LA PRODUCCION DE LOS RAYOS X DURANTE SU FUNCIONAMIENTO. LOS PARAMETROS SE COMPARAN DE FORMA CONTINUA CON UNOS VALORES LIMITE PREDETERMINADOS, Y VARIOS CONTROLES DE FUNCIONAMIENTO DEL CRT SE AJUSTAN EN RESPUESTA A LA COMPARACION PARA MANTENER LOS VALORES DE LOS PARAMETROS MEDIDOS POR DEBAJO DE LOS VALORES LIMITE PREDETERMINADOS.
