Abstract

Se divulga un aparato (1820) de generación de imágenes por resonancia magnética (MRI). El aparato de MRI incluye una pluralidad de elementos magnéticos (608, 808, 1008, 1608) fijados en una estructura de domo de Halbach (400, 500, 800, 1000, 1200, 1400, 1500, 1600). La estructura de domo de Halbach (400, 500, 800, 1000, 1200, 1400, 1500, 1600) define una abertura de acceso (402, 502, 810, 1010, 1202, 1406, 1502, 1602) configurada para permitir el acceso a la cabeza del paciente (410, 510, 1404) para poder realizar una intervención neuronal y define una abertura para paciente configurada para recibir la cabeza de un paciente (410, 510, 1404). En diversos aspectos, el domo de Halbach (400, 500, 800, 1000, 1200, 1400, 1500, 1600) comprende una pluralidad de aberturas de acceso (402, 1502, 1602) y/o espacios (502) cuyo tamaño puede ajustarse.
