  • Split type magnetic resonance imaging magnet
    Patent number: 6570475
    Abstract: An MRI magnet assembly includes a pair of cryostat enclosures each housing a superconducting primary shield coil. The primary shield coil is dimensioned with an outer diameter greater than that of the main coil and is axially spaced away from the magnet pole significantly farther than is the main coil. This design provides for increased accessibility and visibility within the gap defined between the cryostat enclosures, and allows for reduced amounts of superconducting material in the coils. A set of field shaping coils is mounted radially inwardly and closely axially adjacent to the magnet pole and axially between the main coil and the shield coil.

  • Compact gradient coil assembly for MRI apparatus
    Patent number: 6525536
    Abstract: A cylindrical magnet assembly for use in magnetic resonance imaging apparatus has a radially compact construction which eliminates prior manufacturing steps. Recesses are formed in insulation layers for receiving complimentary shaped bus bars. Because the bus bars are dimensioned to fit flush within the recesses, they do not add to the radial growth of the magnet assembly.
