    • A magnetic resonance imaging (MRI) system includes an MRI magnet (100) including a bore (101) and having a magnetic field and a gradient coil (400 )disposed within the bore and having an isocenter (404). A first location within the MRI magnet is determined with respect to a first predetermined reference surface of the MRI magnet, the first location representing a center (104) of the magnetic field. A second location within the gradient coil is determined with respect to a second predetermined reference surface of the gradient coil, the second location representing the isocenter. When the gradient coil is installed within the bore, the second predetermined reference surface abuts the first predetermined reference surface. The first predetermined reference surface is adjusted to an adjusted position, the adjusted position being determined as a function of the first location and the second location and corresponding to a position of the first predetermined reference surface at which the first location coincides with the second location when the gradient coil is installed within the bore.

    • A space defining structure for magnetic homogenization is disclosed. The space defining structure of this invention is specifically designed to homogenize the magnetic field within its interior space, thus minimizing a malfunctioning or damage of electronic equipment or ill-effect on living matters within houses and buildings due to a localized geomagnetic disturbance. Such a localized geomagnetic disturbance may be generated by a variety of magnetic structures, such as the interior structures of the earth's crust, for example, stratum structures, underground water and water veins, a variety of magnetic materials, a variety of electronic devices or the reinforcing bars of the houses or buildings. The space defining structure for magnetic homogenization of this invention consists of a magnetic field focusing member (1) forming the bottom wall of the space structure. The space defining structure also has at least one magnetic field dispersing member (2) extending from the magnetic field focusing member (1) while defining the desired interior space of the structure in cooperation with the magnetic field focusing member (1).
