Recently, we proposed an improved structured low-rank (SLR) reconstruction - locally structured low-rank (LSLR) method, which forces low-rank constraints on submatrices of the Hankel structured matrix. This simple modification leads to a robust improvement over conventional SLR reconstruction, which has been validated on the low-rank tensor reconstruction for the multi-echo GRE data.
