  • Neck coil arrangements for magnetic resonance imaging
    Patent number: 9494664
    Abstract: Systems and methods for coil arrangements in Magnetic Resonance Imaging (MRI) are provided. One arrangement includes a magnet bore, a radio-frequency (RF) transmit coil coupled to the magnet bore and at least one RF neck coil coupled to the magnet bore. The RF neck coil is movable within the magnet bore under and separate from a table within the magnet bore.
    Type: Grant

    Date of Patent: November 15, 2016
    Assignee: General Electric Company
    Inventors: Victor Taracila, Fraser Robb, Miguel Angel Navarro, Darren Charles Gregan
  • Non-cylindrical cable balun design for RF coils
    Patent number: 9329248
    Abstract: A non-cylindrical cable balun design having reduced space requirements and that provides for a lighter-weight RF coil is disclosed. The balun includes a balun shell having a non-cylindrical profile, a dielectric foam positioned within the balun shell so as to fill an interior volume defined by the balun shell, and one or more capacitors formed on the balun shell. A non-cylindrical coaxial cable that transmits electromagnetic signals to the balun extends through a length of the balun and is surrounded by the dielectric foam.
