  • Patent number: 9977100
    Abstract: A coil arrangement for use in a magnetic resonance imaging system, the imaging system being for generating a magnetic imaging field in an imaging region, the coil arrangement including at least three coils for at least one of transmitting, receiving or transceiving an electromagnetic field, each coil being provided on a coil geometry and being substantially orthogonal.
    Type: Grant
    Filed: March 30, 2010
    Date of Patent: May 22, 2018
    Assignee: The University of Queensland
    Inventors: Stuart Crozier, Adnan Trakic, Ewald Weber, Bing Keong Li, Hua Wang
  • Patent number: 9429634
    Abstract: A coil for a magnetic resonance imaging device consists of multiple coil elements arranged about an imaging space. Each coil element comprise radiating structures oriented at an angle to a tangent of the imaging space. Angling the radiating structures reduces mutual coupling between coil elements and enhances the penetration of the radio frequency field to the imaging space.

  • Patent number: 8754644
    Abstract: Apparatus for use in a magnetic resonance imaging system, the imaging system generating a magnetic imaging field in an imaging region (5), the apparatus including at least one coil for at least one of transmitting, receiving or transceiving an electromagnetic field, a field component (4) (such as a coil or a shield) and a drive (6) coupled to the field component for moving the field component (4) relative to the imaging region (5) to thereby modify the electromagnetic field during imaging process. The same concept can also be applied to nuclear imaging or nuclear spectroscopy apparatus.

  • Patent number: 8390287
    Abstract: A Magnetic Resonance Imaging (MRI) phased array head coil (10) comprises an array of coils (1, 2, 3, 4) a decoupling circuit (7) and a decoupling base (14). Counter wound inductors from adjoining coils (1, 2, 3, 4) in the decoupling circuit (7) are interlaced to achieve mutual decoupling between adjoining coils. Each separate coil (1, 2, 3, 4) includes a pair of spaced parallel main conductors (12) located on opposite sides of a cylindrical space (5) enclosed by the coils (1, 2, 3, 4). The decoupling base (14) comprises two meandering conductor bases (8, 9) which are interlaced. Orthogonal main conductors (12) of the coil (1, 2, 3, 4) share a common conductor base (8, 9). The multiple crossings of the paths of the conductor bases (8, 9) reduces mutual coupling effects.

  • Patent number: 7898252
    Abstract: A method and apparatus for ameliorating high-field image distortion in magnetic resonance imaging of tissue. Two separate scans of a target region are taken with different phase and amplitude values for each scan. The phase and amplitude values of each scan are selected to be complimentary so as to provide scans that have improved SNR when averaged using, for example, sum-of-squares averaging.
