An apparatus for decoupling a receive coil from a transmit coil includes a tuning circuit connected electrically with the receive coil and a MEMS switch connected electrically in parallel with the tuning circuit, and operable to line up or to bypass the tuning circuit by opening or closing the MEMS switch. The apparatus further includes a control circuit operatively connected with the MEMS switch and operable to open or to close the MEMS within a window of time responsive to energization of the transmit coil to transmit a signal.

A non-cylindrical cable balun design having reduced space requirements and that provides for a lighter-weight RF coil is disclosed. The balun includes a balun shell having a non-cylindrical profile, a dielectric foam positioned within the balun shell so as to fill an interior volume defined by the balun shell, and one or more capacitors formed on the balun shell. A non-cylindrical coaxial cable that transmits electromagnetic signals to the balun extends through a length of the balun and is surrounded by the dielectric foam.
