摘要:
A magnetic resonance imaging (MRI) radio frequency (RF) coil array configured to operate in a transmit (Tx) mode or in a receive (Rx) mode, the MRI RF coil array comprising at least one single-layer RF coil element. The at least one RF coil element includes a resonant LC coil, a matching Tx/Rx switch circuit, and a preamplifier. The matching and Tx/Rx switch circuit, when operating in Tx mode, electrically isolates the LC coil from the preamplifier upon the LC coil resonating with a primary coil at the primary coil's working frequency. The LC coil, upon resonating with the primary coil at the working frequency, generates a local amplified Tx field based on an induced current in the LC coil. A magnitude or a phase of the induced current is independently adjustable. The matching and Tx/Rx switch circuit, when in Rx mode, electrically connects the LC coil with the preamplifier.
