sigpy.mri.rf.sim.abrm

sigpy.mri.rf.sim.abrm(rf, x, balanced=False)[source]

1D RF pulse simulation, with simultaneous RF + gradient rotations.

Parameters:
  • rf (array) – rf waveform input.
  • x (array) – spatial locations.
  • balanced (bool) – toggles application of rewinder.
Returns:

2-element tuple containing

  • a (array): SLR alpha parameter.
  • b (array): SLR beta parameter.
