Abstract
Un método para determinar las características de un material utilizando mediciones de resonancia magnetica nuclear (NMR), que elimina el efecto de lassenales de NMR espurias causadas por las resonancias mecánicas dentro del aparato demedic ion. El método alivia los problemas de interferencia quetípicamente surgen de los impulsos de exitacion fuertes en una secuencia, y permite la utilizacion de los correspondientes puntos de datos para incrementarla resolucion de la medicion. Elmétodo se basa en el cambio de la frecuencia de la medicion entre las secuencias de los pulsos y en el promediado de lospuntos de datos obtenidos a partir de las diferentes secuencias, ello de una manera que lleva a cabo la cancelacion de lassenales espurias. El novedosociclo de las secuencias de los puntos y el método para la adquisicion de los datos, pueden ser utilizados por ejemplo con cualesquiera de los instrumentospara la exploracion de la NMR.
