Abstract
Un método para medir propiedades de movimiento de núcleos contenidos dentro de espacios de poro de un medio poroso. El método incluye aplicar al medio uncampo magnético estático para polarizar los núcleos, generar una primera magnitud de variación gradual de campo magnético dentro de los espacios deporos del medio, aplicar un campo magnético de radiofrecuencia para excitar los núcleos, recibir senales de resonancia magnética nuclear provenientes de losnúcleos, y calcular las propiedades de movimiento a partir de regímenes de extinción de la amplitud de las senales de resonancia magnética nuclear. Unarealización preferida incluye aplicar un campo magnético estático que tiene una primera amplitud, una segunda amplitud y una variación gradual de amplitud,aplicar el campo magnético de radiofrecuencia con una primera frecuencia para excitar los núcleos dentro de dicha primera amplitud de campo magnéticoestático, recibir senales de resonancia a la primera frecuencia, aplicar uncampo magnético de radiofrecuencia a una segunda frecuencia para excitar losnúcleos dentro de la segunda amplitud del campo magnético estático, y recibir senales de resonancia a dicha segunda frecuencia y calcular las propiedadesde movimientoa partir de la diferencia existente en los regímenes de extinción de las amplitudes de las senales de resonancia de las respectivas frecuenciaprimera y segunda.
