摘要： 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.

摘要： 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.

摘要： 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.
