    Abstract: An adjustable MRI head coil apparatus includes a plurality of plates. Each of the plurality of plates includes a plurality of RF receive elements arranged in a fixed orientation. The adjustable MRI head coil apparatus also includes a support coupled to at least one of the plurality of plates. The support includes a ball head mechanism configured to allow tilting of the adjustable MRI head coil apparatus in a least one direction.

    Abstract: 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.

    Abstract: 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 comprises: a first conductor and a second conductor counterwound around a length of a central conductor, the first and the second conductors radially spaced a distance from the central conductor, the first and second conductors fixed to a first side of the central conductor; and a third conductor and a fourth conductor counterwound around the length of the central conductor, the third and fourth conductors are radially spaced the distance from the central conductor, the third and fourth conductors fixed to a second side of the central conductor opposite the first side. In this way, the density of common mode trap conductors in a common mode trap may be increased, thereby increasing the mutual inductance between the common mode trap and the central conductor.

    Abstract: 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.
