(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.
