Query: GFB-MRF: A parallel spatial and Bloch manifold regularized iterative
  reconstruction method for MR Fingerprinting   Magnetic Resonance Fingerprinting (MRF) reconstructs tissue maps based on a
sequence of very highly undersampled images. In order to be able to perform MRF
reconstruction, state-of-the-art MRF methods rely on priors such as the MR
physics (Bloch equations) and might also use some additional low-rank or
spatial regularization. However to our knowledge these three regularizations
are not applied together in a joint reconstruction. The reason is that it is
indeed challenging to incorporate effectively multiple regularizations in a
single MRF optimization algorithm. As a result most of these methods are not
robust to noise especially when the sequence length is short. In this paper, we
propose a family of new methods where spatial and low-rank regularizations, in
addition to the Bloch manifold regularization, are applied on the images. We
show on digital phantom and NIST phantom scans, as well as volunteer scans that
the proposed methods bring significant improvement in the quality of the
estimated tissue maps.
