Abstract
A method and apparatus are disclosed for combining the respective readout signals for a loop and butterfly coil pair of a quadrature phased array used for magnetic resonance imaging. The technique used to combine the signals introduces a 180 degree phase shift, or multiple thereof, to the loop coil signal, thereby allowing the loop coil signal to be decoupled from other loop coil signals by a low input impedance preamplifier in series with the signal.
