sigpy.mri.rf.multiband.mb_rf(pulse_in, n_bands=3, band_sep=5, phs_0_pt='None')[source]

Multiband an input RF pulse.

  • pulse_in (array) – samples of single-band RF pulse.
  • n_bands (int) – number of bands.
  • band_sep (float) – normalized slice separation.
  • phs_0_pt (string) – set of phases to use. Can be ‘phs_mod’ (Wong), ‘amp_mod’ (Malik), ‘quad_mod’ (Grissom), or ‘None’

band_sep = slice_sep/slice_thick*tb, where tb is time-bandwidth product of the single-band pulse

Returns:multibanded pulse out
Return type:array
