摘要： Various methods and systems are provided for a flexible, lightweight, and lowcost 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 at least three distributed capacitance conductor wires encapsulated and separated by a dielectric material, a coupling electronics portion including a preamplifier, and a coil-interfacing cable extending between the coupling electronics portion and an interfacing connector of the RF coil assembly.

摘要： Various methods and systems are provided for radio frequency (RF) coils for magnetic resonance imaging (MRI). In one embodiment, an RF coil assembly for an MRI system includes a posterior end including a first set of flexible RF coils; an anterior end including a second set of flexible RF coils; a central section extending between the posterior end and anterior end, wherein the posterior end and the anterior end are bendable to the central section. Each flexible RF coil of the first set and second set of flexible RF coils includes a loop portion comprising a coupling electronics portion and at least two parallel, distributed capacitance wire conductors encapsulated and separated by a dielectric material.

摘要： Various methods and systems are provided for a flexible, lightweight, and low-cost radio frequency (RF) coil of a magnetic resonance imaging (MM) system with reduced power dissipation during decoupling. In one example, the RF coil includes a loop portion with distributed capacitance which comprises two conductor wires encapsulated and separated by a dielectric material and a feed board including a decoupling circuit configured to decouple the distributed capacitance of the loop portion during a transmit operation, an impedance inverter circuit, and a pre-amplifier.
