Abstract

La invención se refiere a una red de bobinas superconductoras de radiofrecuencia para la cabeza, enfriado criogénicamente que pueden ser utilizados en los escáneres de imágenes por resonancia magnética MRI para todo el cuerpo y/o en sistemas de resonancia magnética especiales para la cabeza solamente. La invención también se refiere a un sistema de imanes superconductores para un sistema de resonancia magnética especial para la cabeza, y un sistema de MRI especial para la cabeza para la cabeza que puede incluir un imán principal superconductor y una red de bobinas superconductoras de radiofrecuencia para la cabeza enfriadas criogénicamente. El imán principal superconductor comprende un primero y un segundo grupo de bobinas coaxiales en donde las bobinas del segundo grupo tienen un radio interno mayor que las bobinas del primer grupo.
