Abstract: Methods and systems are provided for radio frequency (RF) coil arrays for magnetic resonance imaging (MRI) systems. In an embodiment, a RF coil array assembly for a MRI system includes a compressible body; an upper posterior RF coil array including a first plurality of RF coils embedded in the compressible body; a lower posterior RF coil array including a second plurality of RF coils embedded in the compressible body; and a head and neck RF coil array removably coupled to the upper posterior RF coil array. The head and neck RF coil array includes a third plurality of RF coils embedded in the compressible body, and one or more neck straps configured to fold over a neck of a subject to be imaged by the MRI system.

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.
