RF coil elements with split DC loops for magnetic resonance imaging systems for integrated parallel reception, excitation, and shimming and related methods and devices

摘要

Systems, methods and devices are configured for integrated parallel reception, excitation, and shimming (iPRES) with RF coil elements with split DC loops. Parallel transmit/receive (which can include B₁ shimming and/or parallel imaging capabilities) and B₀ shimming employ the same set of localized coils or transverse electromagnetic (TEM) coil elements, with each coil or TEM element working in both an RF mode (for transmit/receive and B₁ shimming) and a direct current (DC) mode (for B₀ shimming) simultaneously. Both an RF and a DC current (in split DC loops) can flow in the same coil element simultaneously but independently with no electromagnetic interference between the two modes.
