Abstract

Se trata de un aparato de medicion de resonancia magnética que está sujeto a movimiento relativo entre el aparato y un espécimen a lo alrgo de unatrayectoria incluye un imán, antenas y un circuito. El imán polariza el espécimen y las antenas estándi stribuidas de forma espacial a lo largo de latrayectoria. El circuito utiliza las antenas para realizar las mediciones de resonancia magnética y utiliza la distribucion espacial de las atenas paraestablecer los diferentes tiempos de polarizacionpara las mediciones de resonancia magnética. También se propone el método de medicion utilizando dichoaparato.
