mdreg.spgr_vfa_nonlin#

mdreg.spgr_vfa_nonlin(signal, FA=None, bounds=([0, 0], [inf, 1]), p0=[1, 0.5], parallel=False, **kwargs)[source]#

Non-linear SPGR model fit

Parameters:
  • signal (numpy.ndarray) – Signal data Spatial array with signal intensities over different flip angles.

  • FA (numpy.array) – Flip Angles

  • bounds (tuple) – Bounds for the fit

  • p0 (list) – Initial parameters

  • parallel (bool) – Use parallel processing

  • **kwargs – Additional keyword arguments

Returns:

  • fit (numpy.ndarray) – Fitted data

  • pars (numpy.ndarray) – Fitted model parameters The parameters are: S0, T1, giving N=2.
