Joint T1 and T2 Mapping with Tiny Dictionaries and Subspace-Constrained Reconstruction
Volkert Roeloffs, Martin Uecker, Jens Frahm
Purpose: To develop a method that adaptively generates tiny dictionaries for joint T1-T2 mapping. Theory: This work breaks the bond between dictionary size and representation accur…

Model-Based Iterative Reconstruction for Radial Fast Spin-Echo MRI
Kai Tobias Block, Martin Uecker, Jens Frahm
In radial fast spin-echo MRI, a set of overlapping spokes with an inconsistent T2 weighting is acquired, which results in an averaged image contrast when employing conventional ima…
