DECOUPLING MAGNETIC RESONANCE IMAGING (MRI) RADIO FREQUENCY (RF) COIL ELEMENTS WITH HIGH ACCELERATION FACTOR IN PARALLEL TRANSMIT (pTX) OR RECEIVE (RX) COILS USING FEWER CHANNELS

摘要

An MRI RF coil array for use in a multi-channel MRI system, comprising a plurality of coils arranged in a M by N array, the number of columns corresponding with the number of channels in the MRI system. Columns are aligned with the B₀ field. The plurality of coils are configured as a plurality of combined coils, corresponding with the number of columns, comprising a coil in a first row of the array connected with a coil in each of the remaining rows. The column position of each coil of a combined coil is distinct from the column position of each other coil of the combined coil. Coils of a combined coil are disjoint from the coils of each, other, combined coil. A combined coil is configured to connect with a corresponding member of the plurality of Rx channels, and is decoupled from each, other combined coil.
