Choose gradient shape to optimally complement coil profiles

  • Choose gradient shape to optimally complement coil profiles

  • Select a subset of spherical harmonics in the axial plane:



















  • Low Z2 gradient strength (0.07 g/cm2) = long readout window (50 ms)

    • B0 Inhomogeneity
    • B0 Offset
  • Eddy currents

  • Solution: Build dedicated high-strength, shielded gradient coil for O-Space imaging.



O-space shows promise for highly accelerated imaging

  • O-space shows promise for highly accelerated imaging

  • Design spatial gradients to be more complementary to coil spatial encoding for highly-efficient parallel imaging
