摘要： Various systems are provided for neck radio frequency (RF) coil assemblies for a magnetic resonance imaging (MRI) system. In one example, a neck RF coil assembly includes a central RF coil array including a first plurality of RF coils configured to cover a neck of a subject to be imaged, an upper RF coil array including a second plurality of RF coils extending upward from the central RF coil array and configured to cover a lower head region of the subject, and a lower RF coil array including a third plurality of RF coils extending downward from the central RF coil array and configured to cover an upper shoulder region of the subject, wherein each RF coil of the first, second, and third pluralities of RF coils comprises a loop portion comprising two 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 (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.

摘要： Methods and systems are provided for radio frequency (RF) coils for magnetic resonance imaging (MRI) systems. In one embodiment, a system comprises: a radio frequency (RF) coil array for a magnetic resonance imaging (MRI) system, including: a flexible shell including an inner layer; and a plurality of flexible RF coils embedded within the inner layer, with each RF coil of the plurality of RF coils including two distributed capacitance wire conductors. In this way, the RF coil array may deform in order to conform to a body of a patient.

摘要： Various methods and systems are provided for a common mode trap for a magnetic resonance imaging (MRI) apparatus. In one embodiment, a common mode trap for an MRI apparatus comprises: a first conductor and a second conductor counterwound around a length of a central conductor, wherein the first and the second conductors are radially spaced a first distance from the central conductor at first and second ends of the length, and wherein the first and the second conductors are radially spaced a second distance larger than the first distance from the central conductor at a midpoint of the length. In this way, coupling and subsequent detuning of common mode traps provided adjacent to one another may be prevented.
