Article Title: Fast Reconstruction for Multi-channel Compressed Sensing Using a Hierarchically Semiseparable Solver
doi: 10.1002/mrm.25222
Figure Lengend Snippet: Computational scaling of the HSS-Inverse method with respect to the number of parallel imaging channels and acceleration factor. A 10−6 tolerance is assumed for 5 iterations of Split Bregman with a TV weighting β = 3 · 10−3 and soft-thresholding ε = 2 · 10−1. Cartesian optimized coil compression is used to reduce from 32 to 8-channels. R = 2, 3, and 4 under-sampling is examined.
