Abstract

An apparatus for use in a magnetic resonance examination includes a radio frequency receive coil (50) and adjustable tuning circuitry (51) for adjusting the resonant frequency of the receive coil. The apparatus also includes a preamplifier (29) which amplifies signals generated by the receive coil. An adjustable feedback circuit (31) alters an effective Q of the receive coil.
