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: A method, system, and apparatus including a radio-frequency (RF) phased coil array for a magnetic resonance (MR) imaging apparatus that includes a first RF coil element tuned to a first frequency and configured to receive MR signals and a second RF coil element tuned to a second frequency different than the first frequency and configured to receive MR signals.

Abstract: A method, system, and apparatus including a magnetic resonance (MR) coil system that includes an MR coil element, a high input Pre-amplifier having a high input impedance field-effect-transistor (FET) with an impedance of one of substantially equal to 500 ohms and greater than 500 ohms, and a conductive path. The conductive path has a first end coupled to the MR coil element and a second end coupled to the high input Pre-amplifier such that the MR coil element is coupled in series with the high input Pre-amplifier. Further, the conductive path is free of a matching network intervening between the MR coil element and the high input Pre-amplifier.
