(rf, gamgdt, xx, dom0dt=0)[source]¶ 1D RF pulse simulation, with non-simultaneous RF + gradient rotations.
Parameters: - rf (array) – rf pulse samples in radians.
- gamdt (array) – gradient samples in radians/(units of xx).
- xx (array) – spatial locations.
- dom0dt (float) – off-resonance phase in radians.
Returns: 2-element tuple containing
- a (array): SLR alpha parameter.
- b (array): SLR beta parameter.
