1. A radio frequency component configured for magnetic resonance imaging (MRI), the radio frequency component comprising:
a first coil configured to generate magnetic field components, the first coil including a first conductor arranged in a plurality of turns having non-uniform spacing; and
a second coil configured to be responsive to magnetic resonance signal components,
wherein the first and second coil are tuned to resonate at a frequency corresponding to a B0 field having a field strength of less than or equal to 0.1 T.
