1. A coil for magnetic resonance imaging comprising:

  • a first electrically conductive ring forming an inferior end of the coil for access by a test subject, the first electrically conductive ring having a first diameter;

    a plurality of legs extending from the first electrically conductive ring, each of the plurality of legs having a linear portion and a tapered portion; and

    a second electrically conductive ring forming a superior end of the coil and having a second diameter which is different than the first diameter, the second electrically conductive ring being connected to the tapered portion of the plurality of legs, wherein the tapered portion of the plurality of legs provide the coil with a substantially homogenous field pattern.
