Abstract
A RF choke for use in shielded cable control lines between a RF receive and transmit coil and the control circuitry of a MRI system is disclosed. The RF choke is formed of conductive tubing in the shape of a coil, within which the control signal wires are housed. A capacitor is added in parallel with the conductive tubing coil to complete a resonance circuit acting as a choke to spurious RF currents.
