Magnetic structure for generating magnetic fields for use in the detection of nuclear magnetic resonance.

摘要

The invention relates to a structure MAGNETICA FOR GENERATING MAGNETIC FIELDS APPLICABLE IN THE SENSE OF MAGNETIC RESONANCE IMAGING NUCLEAR, having means (1, 101, 201, 301, 101, 201, 101 ", 201", 3, 3) to generate mAGNETIC FIELD WITH FEATURES IMAGES REQUIRED FOR VALID IN DEFAULT ZONE A three-dimensional (102), this being at least a portion of a cavity (2) partially contained in the magnetic structure. PURSUANT TO invention MEDIA MAGNETIC FIELD GENERATING comprise at least one coil (3, 3) Resistive superconductive TYPE O. COIL (3, 3) is associated with an element (1) made of a highly permeable material, so-called YOKE, defining a cavity (2) having at least one open side, while one or more inner pole pieces (101 , 201, 301, 101, 202, 101 ", 201") branch from the inner side facing the cavity (2) YOKE (1), at least in the area (102) intended to receive the body or PART THEREOF TO ANALYZE, and end with a free end into the cavity (2), around which pole pieces are arranged the coils (3, 3) to generate the magnetic flux.
