We
present a composite scheme for minimizing the mutual inductance of
transceiver array coils with more than two channels, which combines a novel
shielding-based decoupling design with simplified capacitive decoupling
method. The significant advantage of this composite strategy is that the
adjustment of decoupling parameters for each coil element barely affects
other elements. This characteristic of
the new strategy greatly minimizes the coupling mechanism between different
elements which is inherent to coil arrays and thereby simplifying the complex
decoupling of transceiver array coils.
