Abstract: The present disclosure relates to a magnetic resonance imaging (MRI) radio frequency (RF) array coil that includes first and second physical RF coils inductively coupled. A first matching circuit and a second matching circuit are coupled to the first physical RF coil and the second physical RF coil, respectively, and are coupled in a parallel configuration at a first RF port. A third matching circuit and a fourth matching circuit are coupled to the first physical RF coil and the second physical RF coil, respectively, and are coupled in an anti-parallel configuration at a second RF port. A first logical RF coil is formed by the first and second physical RF coils and the first and second matching circuits. A second logical RF coil, which is decoupled from the first logical RF coil, is formed by the first and second physical RF coils and the third and fourth matching circuits.

Abstract: Various embodiments of the present disclosure are directed towards a magnetic resonance imaging (MRI) radio frequency (RF) coil array configured to operate in at least one of a transmit mode or a receive mode on a cylindrical former. The MRI RF coil array includes at first row of RF coil elements. Each row of RF coil elements includes at least three RF coil elements that circumferentially surround a cylindrical axis. The MRI RF coil array also includes a first birdcage coil that circumferentially surrounds the first row of RF coil elements. Each RF coil element of the first row is configured to inductively couple to the first birdcage coil and to each other RF coil elements. The first birdcage coil has an impedance configured to negate inductive coupling between the RF coil elements of the first row.
