摘要： A superconducting magnet utilizing a pair of donut-shaped annular magnet assemblies including in each a cryogen pressure vessel with a non-magnetic cylindrical divider forming pairs of concentric chambers. Pairs of axial non-magnetic strut members spaced about the interior of the pressure vessel extend at an angle within the concentric chambers between the end flanges of each assembly to resist forces generated within and between the pair of magnet assemblies.

摘要： An arrangement is provided for supporting the inner and outer gradient coils of one or more gradient coil sets, the coils of each gradient coil set providing one of the orthogonal gradient magnetic fields for an MR imaging system. The arrangement includes an inner cylindrical coil form disposed to supportably carry an inner gradient coil of a coil set, an outer cylindrical coil form in coaxial spaced-apart relationship with the inner coil form disposed to supportably carry an outer gradient coil of the coil set, and a stiffening cylinder positioned between the inner and outer coil forms to divide the space therebetween into first and second volumes. A thermally conductive adhesive material, such as an epoxy containing alumina particulate material, is inserted into the first and second volumes to bond both the inner and outer coil forms to the stiffening cylinder, in order to hold the inner and outer gradient coils respectively carried by the coil forms in rigid fixed relationship with respect to one another.
