Abstract

Un sistema para el análisis no invasivo de tejido incluye una sonda portátil (15) no ferromagnética que distingue entre nervios, músculos y vasos sanguíneos; una fuente de campo magnético en la sonda genera un campo magnético uniforme e invariable en el tiempo dentro de un volumen de tejido y contiene una bobina inductiva (19) que recibe señales de excitación de RF en un intervalo de frecuencia específico relacionado con la intensidad de campo generando señales de excitación perpendiculares a una dirección del campo magnético y magnetizando una rebanada del tejido vivo que tiene profundidad y grosor predeterminados por la intensidad de campo, por lo que sólo el tejido vivo en cada rebanada responde a señales de eco de espín nuclear; una unidad de control genera patrones de tiempo de las señales de excitación y extrae datos indicativos de las señales de eco de espín nuclear del tejido vivo, determina curvas de relajación que tienen constantes de tiempo T1, T2 y realiza el procesamiento estadístico de las curvas de relajación para determinar el tipo de tejido excitado por la sonda.
