Abstract
A single-layer magnetic resonance imaging (MRI) radio frequency (RF) coil array configured to operate in a transmit (Tx) mode or in a receive (Rx) mode comprises at least one single-layer MRI RF coil array element configured to provide integrated Bfield shimming. The at least one single-layer MRI RF coil array element includes a resonant LC coil, a matching Tx/Rx switch circuit, a magnitude/phase control component, and a preamplifier. The LC coil, upon resonating with a primary coil at the working frequency, generates a local amplified Tx field based on an induced current in the LC coil. The magnitude/phase control component is configured to independently adjust a magnitude or a phase of the induced current. The at least one single-layer MRI RF coil element may include a Tx field monitoring component configured to monitor the strength or phase of the local amplified Tx field.
