Nonlinear least squares fitting for variable flip angle T1 estimation
The niiT1vfa program enables a fast nonlinear least squares fit for T1 estimation using a robust and efficient version of the Levenberg-Marquardt minimization algorithm provided by a derivative solver in the Gnu Scientific Library (GSL, http://www.gnu.org/software/gsl/). Input data are variable fli...
