Apparatus and method for decoupling an MRI receive coil

Apparatus and method for decoupling an MRI receive coil

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...

description 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.
