摘要： A magnet for MRI apparatus has a magnetic circuit which includes a magnetic flux path formed by a ferromagnetic material and a magnetic flux path formed by magnetic flux return coils or magnetic flux control coils, so that a 5-gauss line of leakage fluxes can be kept within a sphere 3 m in radius even when the static magnetic field intensity exceeds 1 tesla and a comparatively light magnet for MRI apparatus can be provided. Further, the fluxes escaping vertically from the static magnetic field sources are led compactly to a horizontal direction by installing magnetic flux paths of ferromagnetic materials and coils with polarities opposing those of the static magnetic fields. This arrangement minimizes an increase in the total height of the magnet for MRI apparatus, keeping the magnet within the total height of 3 m.

摘要： A magnet device includes two sets of static magnetic field generation sources spaced from each other in the vertical direction such that the uniform magnetic field region (patient space) is between then. Each set has concentric current carrying coils to generate a uniform magnetic field in a first direction (the vertical direction). Several such coils are used in each set, disposed such that when a first axis which is parallel to the first (vertical) direction and passes substantially through the centers of the current carrying coils crosses, at a first point, a second axis which is orthogonal to the first axis and is at substantially equal distance from the respective static magnetic field generation sources, the current carrying coils are disposed in such a manner that when geometrical centers of cross sections of the current carrying coils are projected on a first straight line that is in a first plane containing the first axis, the second axis and the first point and passing through the first point, the directions of the currents of the carrying coils at the respective corresponding projections align alternatively in positive and negative directions on the first straight line.

摘要： The present invention relates to techniques for enlarging an opening, which accommodates a subject, in a superconducting magnet apparatus for use in MRI system, so as to prevent the subject from feeling claustrophobic, and for realizing low magnetic field leakage therefrom, and for reducing the weight thereof, and for realizing a large high magnetic field strength uniform magnetic field region. Static magnetic field generating sources of the superconducting magnet apparatus are constituted by two sets of superconducting coils, the respective sets of which are placed in such a manner as to face each other across a uniform magnetic field generating region. Each of the sets of superconducting coils consists of a main coil for feeding electric current in a specific direction, a bucking coil for feeding electric current in a direction opposite to the direction of the electric current flow passing through the main coil, and a coil for correcting magnetic homogeneity. The diameter of the aforementioned main coil is set as being nearly equal to that of the aforesaid bucking coil. Further, the diameter of the coil for correcting the magnetic homogeneity is set as being less than that of the main coil. Moreover, an amount of electric current flowing through the coil for correcting the magnetic homogeneity is set as being less than that of electric current passing through the main coil. Furthermore, the distance between the two main coils facing each other is set as being shorter than that between the two bucking coils.
