pulpy.sim.abrm_hp

pulpy.sim.abrm_hp(rf, gamgdt, xx, dom0dt=0, b1=None)[source]

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

Parameters:

  • rf (array) – rf pulse samples in radians.

  • gamgdt (array) – gradient samples in radians/(units of xx).

  • xx (array) – spatial locations.

  • dom0dt (array) – off-resonance phase in radians.

  • b1 (array) – B1 at each spatial location, for each channel in rf. b1 * rf should have units of radians

Returns:

2-element tuple containing

  • a (array): SLR alpha parameter.

  • b (array): SLR beta parameter.
