An eight-channel RF transceive head coil with automatic tuning and matching was implemented and evaluated at 7T. The electrically controlled feedback system rapidly manipulates the frequency tune and impedance match and is compatible with any existing MRI system. The results show the feasibility of the automated system to tune and match transmit and/or receive elements along with multi-channel RF coils.
