摘要： Various methods and systems are provided for a flexible, lightweight, low-cost radio frequency (RF) coil array of a magnetic resonance imaging (MRI) system. In one example, a RF coil assembly for a MRI system includes a loop portion comprising distributed capacitance wire conductors, a coupling electronics portion including a pre-amplifier. A coupler slidably connects two adjacent coil loops together. An open area is formed inside the loops enabling tissue manipulation or biopsies from interventional or surgical procedures.

摘要： A continuous common mode trap assembly includes a central conductor and plural common mode traps. The central conductor has a length, and is configured to transmit a signal between a magnetic resonance imaging (MRI) receive coil and at least one processor of an MRI system. The plural common mode traps extend along at least a portion of the length of the central conductor. The common mode traps are disposed contiguously. The common mode traps are configured to provide an impedance to reduce transmitter driven currents of the MRI system.

摘要： Various methods and systems are provided for a flexible, lightweight and low-cost stretchable radio frequency (RF) coil of a magnetic resonance imaging (MRI) system. In one example, a RF coil assembly for a MRI system includes a loop portion comprising distributed capacitance conductor wires, a coupling electronics portion including a pre-amplifier; and a stretchable material to which the loop portion and coupling electronics portion are attached and/or enclosed therein.

摘要： In one example, an RF coil array includes a first RF coil configured to generate a magnetic field along a first axis, the first RF coil having a first surface, a second RF coil configured to generate a magnetic field along a second axis, orthogonal to the first axis, the second RF coil having a second surface, and a first foldable interconnect coupling the first RF coil to the second RF coil. The first foldable interconnect may be adjusted to couple the first RF coil to the second RF coil with a first amount of overlap and with the first surface and second surface facing a common direction, or couple the first RF coil to the second RF coil with a second amount of overlap, larger than the first amount of overlap, and with the first surface in face to face position with the second surface.

摘要： Various methods and systems are provided for a flexible, lightweight, and low-cost radio frequency (RF) coil of a magnetic resonance imaging (MRI) system. In one example, a RF coil assembly for an MRI system includes a distributed capacitance loop portion comprising two parallel conductor wires encapsulated and separated by a dielectric material, the two parallel conductor wires maintained separate by the dielectric material along an entire length of the loop portion between terminating ends thereof, a coupling electronics portion including a pre-amplifier, and a coil-interfacing cable extending between the coupling electronics portion and an interfacing connector of the RF coil assembly.
