Abstract
In some embodiments, the present disclosure relates to a multi-turn (MT) birdcage magnetic resonance imaging (MRI) radio-frequency (RF) coil. The MT birdcage MRI RF coil includes a first conductive ring, a second conductive ring, and a plurality of conductive rungs. Each of the plurality of conductive rungs includes a first end coupled to the first conductive ring, and a second end coupled to the second conductive ring. At least one of the first conductive ring and the second conductive ring includes more than one turn. The first conductive ring, the second conductive ring, and the plurality of conductive rungs form a plurality of meshes.
