A Novel Approach for T1 Relaxometry Using Constrained Reconstruction in Parametric Dimension

A novel method for T1 relaxometry is proposed using constrained reconstruction in the parametric (flip angle) dimension. Preliminary results indicate that the proposed method allows T1 estimation from undersampled data collected for multiple flip angles with better accuracy than from the data collected for two ideal angles acquired within the same scan time.
