This directory contains the data and code for reproducing the results in the following paper.

Daniel S Weller, Sathish Ramani, Jon-Fredrik Nielsen, J A Fessler.
Monte Carlo SURE-based parameter selection for parallel magnetic resonance imaging reconstruction.
Mag. Res. Med., 71(5):1760-70, May 2014.

This code relies on 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 the IRT toolbox. fix the paths to the data in the imfiles variable at the top of the script. Running make_BayesDESIGN_plots.m and make_L1SPIRiT_plots.m will generate all the figures for the two algorithms in the paper and supplement. The main algorithm functions are L1SPIRiT_WSURE.m and BayesDESIGN_SB_WSURE3.m. todo: old or update the paths in the script make_L1SPIRiT_plots.m (at the end of the first cell block).

Some functions from IRT were changed for the simulations; those are included in the zip file.
