class mri.operators.gradient.gradient.GradSynthesis(linear_op, fourier_op, verbose=0, **kwargs)[source]¶

Gradient Synthesis class. This class defines the grad operators for: (1/2) * sum(||F Psi_t alpha - yl||^2_2,l)

Attributes

fourier_op	(an object of class in mri.operators.fourier) a Fourier operator from FFT, NonCartesianFFT or Stacked3DNFFT This is F in above equation.
linear_op	(an object of class in mri.operators.linear) a linear operator from WaveltN or WaveletUD2 This is Psi in above equation.
verbose	(int, default 0) Debug verbosity. Prints debug information during initialization if 1.
