Abstract: In one example, a method for acquiring a medical image includes activating a body radiofrequency (RF) coil in a body coil receive mode to obtain body calibration information of a subject. The method further includes, while the body RF coil is in the body coil receive mode, activating a surface RF coil in a surface coil receive mode to obtain surface calibration information of the subject, and correcting a reconstructed image with an intensity correction filter determined from the body calibration information and surface calibration information.

Abstract: 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.

Abstract: Various methods and systems are provided for a flexible, lightweight, and low-cost disposable radio frequency (RF) coil of a magnetic resonance imaging (MRI) system. In one example, an RF coil assembly for an MRI imaging system includes a loop portion comprising distributed capacitance conductor wires, a coupling electronics portion including a pre-amplifier; and a disposable material enclosing at least the loop portion, the disposable material comprising one or more of paper, plastic, and/or cloth.

Abstract: 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.

Abstract: 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.
