Augmented Lagrangian with variable splitting for faster non-Cartesian L1-SPIRiT MR image reconstruction.
IEEE Trans. Med. Imag., 33(2):351-61, Feb. 2014.
This code requires both IRT
and Mike Lustig's L1SPIRiT code,
from either v0.1 or v0.3 of the
SPIRiT toolbox.
Instructions:
Use IRT setup.m to prepare IRT toolbox path.
Update the paths in the script
make_brainweb_plots.m
for "imfiles" and the "addpath"
for ESPIRiT.
Run main script
make_brainweb_plots.m
to generate the algorithm comparisons
for the Brainweb data.
Repeat with main script
make_realdata_plots.m
for the real data.
The actual ADMM function is
L1SPIRiT_ADMM_NonCartesian.m.
Some functions from IRT were changed for the simulations;
those are included in the zip file.
