  • System and method for self-sealing a coldhead sleeve of a magnetic resonance imaging system
    Patent number: 8570043
    Abstract: Systems and methods for self-sealing a coldhead sleeve of a magnetic resonance imaging system are provided. One coldhead sleeve arrangement includes a coldhead sleeve configured to receive therein a coldhead of an MRI system and having an open end. The coldhead sleeve arrangement also includes a sealing member coupled at the open end of the coldhead sleeve and configured in a normally closed position covering the open end.

  • System and method for de-icing recondensor for liquid cooled zero-boil-off MR magnet
    Patent number: 7305845
    Abstract: A system and method for de-icing a recondensor includes at least one heating element configured to melt iced particles from a recondensing system. A power delivery circuit is included configured to deliver power to the at least one resistive heating element such that the at least one resistive heating element delivers a supply of heat sufficient to melt the iced particles from the recondensing system.

  • Thermal conductance gasket for zero boiloff superconducting magnet
    Patent number: 5918470
    Abstract: A recondensing zero boiloff superconducting magnet assembly utilizing a cryocooler with a compressible indium gasket positioned between the cryocooler and the recondenser and with the gasket containing a plurality of spaced parallel grid wires with interconnecting web segments of a lesser thickness interconnecting the mid sections of ends of adjacent wires to facilitate compression of the gasket to control improved thermal conductivity while minimizing the pressure and forces on the assembly.
