We propose a novel model-driven compressed sensing approach for T1 relaxometry. The proposed algorithm alternates signal estimation with adaptive update of sparsifying transform based both on the analytical signal model and current signal estimate. The proposed algorithm can also be used in other quantitative MRI applications.
