Schematic diagram of the phase-cycled MB-3 bSSFP acquisition and the corresponding off-resonance profile. (a-c) Different schemes to achieve phase-cycled CAIPI-SMS bSSFP imaging. Each set of red, blue and green lines represent three slices that are excited and readout simultaneously. Solid and dashed lines represent modulated phase-cycled bSSFP acquisitions. (d) Magnitude (top) and phase (bottom) of bSSFP off-resonance profile. Specifically, red, blue and green represent slices with a FOV/3, centered and - FOV/3 shift along the phase encoding direction, or 2π/3, 0, -2π/3 shift in their off-resonance profiles.
