  • Publication number: 20040070397
    Abstract: A local coil for magnetic resonance imaging equipment employs mirror conductors on opposite sides of an insulating substrate to produce lower resistance, higher Q and improved signal-to-noise ratio for a given foil thickness.
    Type: Application
    Filed: October 9, 2002
    Publication date: April 15, 2004
    Inventors: Derek Seeber, Velibor Pikelja
  • Publication number: 20040036473
    Abstract: A cable routing system for an MRI coil having multiple loops and multiple signal cables provides a non-resonant conductive ring surrounding the loops and grounded to define a low electrical field region along which the signal cables may be routed for reduced interference.
    Type: Application
    Filed: August 22, 2002

  • Patent number: 6664465
    Abstract: A floating shield current trap provides two resonance loops formed of split concentric tubular conductors joined radially at their axial ends. Adjustment of the separation of these loops provides a change in coupling between the loops effecting a simplified tuning of the resonance of the trap for different expected frequencies of interfering shield current.
    Type: Grant

  • Patent number: 6605775
    Abstract: A floating shield current trap provides first and second concentric tubular conductors electrically connected to provide a resonance-induced high impedance of current flow in a path consisting of the inner and outer conductors and their junctions thereby suppressing coupled current flow on a shield of a conductor contained within the first inner tubular conductor.
