Integrated parallel reception, excitation, and shimming (iPRES) coil arrays enable RF excitation/reception and localized B0 shimming with a single coil array, but so far use an external DC power supply and require a B0 map and a shim optimization for each subject, which takes additional time. Here, we propose a novel iPRES head coil array powered by an on-board MR-compatible battery that delivers fixed DC currents optimized in advance to shim an average subject's brain. This stand-alone, plug-and-play system does not require any subject-specific shim optimization, thus enabling a wider adoption of iPRES in clinical applications.
