Saturation

torchsim.Saturation(definition_id, flip_rad, *, offset_hz=0.0, phase_rad=0.0, duration_s=0.0, shim_id=0)

Return an off-resonance pulse that deposits power in a semisolid pool.

The deposit follows the waveform definition_id names and the offset it is played at, read against the tissue’s lineshape, so this is an RfUse.EXCITATION carrying a real shape rather than an ideal rotation.
