A magnetic structure for generating magnetic fields to be used in nuclear magnetic resonance image detection, having means (1, 101, 201, 301, 101', 201', 101", 201", 3, 3') for generating a magnetic field with the characteristics required to obtain valid images inside a predetermined tridimensional
A magnetic structure for generating magnetic fields to be used in nuclear magnetic resonance image detection, having means (1, 101, 201, 301, 101', 201', 101", 201", 3, 3') for generating a magnetic field with the characteristics required to obtain valid images inside a predetermined tridimensional area (102), being at least a part of a cavity (2), which is at least partially contained in the magnetic structure. According to the invention, the means for generating the magnetic field consist of at least one coil (3, 3'), of the resistive or superconductive type. The coil (3, 3') is associated to an element (1) made of a highly permeable material, the so-called yoke, which defines a cavity (2), having at least one open side, whereas one or more inner pole pieces (101, 201, 301; 101', 202'; 101", 201") branch out of the inner side facing the cavity (2) of the yoke (1), at least in the area (102) which is meant to receive the body or the part thereof to be scanned, and terminate with a free end inside the cavity (2), around which pole piece or pole pieces, the coil or coils (3, 3') for generating the magnetic flow are arranged.
