Abstract

LA INVENCION SE REFIERE A UN METODO PARA LA EXCITACION Y LA DETECCION DE ELEMENTOS DE RESONANCIA MAGNETICA (10) EN UNA ZONA DE INTERROGACION (11), CON LO QUE SE GENERA UNA SEÑAL DE EXCITACION MAGNETICA POR AL MENOS UN MEDIO DE EXCITACION (12) Y SE SUMINISTRA AL ELEMENTO DE RESONANCIA, PARA FORZAR EL ELEMENTO DE RESONANCIA (10) EN LA AUTOOSCILACION MECANICA, Y CON LO QUE SE DETECTA UNA SEÑAL MAGNETICA PROVOCADA POR LA AUTOOSCILACION. SE GENERA LA SEÑAL DE EXCITACION POR AL MENOS DOS MEDIOS DE EXCITACION (12) QUE ESTAN SITUADOS UNO A DISTANCIA DE OTRO, CON LO QUE SE OBTIENE UN PLANO DE SIMETRIA (14) PARA LA SEÑAL DE EXCITACION ENTRE MEDIOS DE EXCITACION (12). LA SEÑAL MAGNETICA PROVOCADA POR LA AUTOOSCILACION SE GRABA SIMETRICAMENTE EN AMBOS LADOS DEL PLANO DE SIMETRIA (14), Y LOS ELEMENTOS DE RESONANCIA SE COLOCAN ENTRE UN MEDIO DE EXCITACION (12) Y EL PLANO DE SIMETRIA (14), CONTENIENDO ASI LA SEÑAL GRABADA LA SEÑAL MAGNETICA PROVOCADA POR LA AUTOOSCILACION, PERO CARENTE DE LA SEÑAL DE EXCITACION.
