Radio frequency coil unit with pressure reservoir for magnetic resonance imaging

A radio frequency (RF) coil unit for magnetic resonance imaging (MRI) comprising:

• an outer layer forming an exterior of the RF coil unit;
• a pressure reservoir enclosed by the outer layer, wherein the pressure reservoir forms a sealed chamber, and wherein the pressure reservoir includes a plurality of openings extending through the pressure reservoir;
• an array of RF coil elements and an array of coupling electronics portions enclosed by the outer layer, wherein each RF coil element comprises,
• a loop portion disposed on one side of the pressure reservoir, and
• one of the array of coupling electronics portions, wherein each of the plurality of openings includes one of the array of coupling electronics portions seated within a corresponding opening.

A radio frequency (RF) coil unit for magnetic resonance imaging (MRI), comprising:

• an outer layer forming an exterior of the RF coil unit;
• an opening extending through the outer layer to an interior of the RF coil unit;
• a pressure reservoir enclosed by the outer layer within the interior, the pressure reservoir including a plurality of through-holes formed by inner sidewalls of the pressure reservoir, the inner sidewalls offset from outer sidewalls of the pressure reservoir, wherein each of the plurality of through-holes extends entirely through the pressure reservoir from a first side of the pressure reservoir to a second side of the pressure reservoir, the first side of the pressure reservoir opposite the second side of the pressure reservoir;
• a fluid passage extending to the exterior of the RF coil unit though the opening of the outer layer, the fluid passage fluidly coupled to the pressure reservoir;
• and
• an array of RF coil elements enclosed by the outer layer, wherein each RF coil element comprises,
• a loop portion disposed on one side of the pressure reservoir, and
• a coupling electronics portion seated within a corresponding through-hole of the plurality of through-holes of the pressure reservoir.
