These scripts reproduce the experiments described in the article:

Free-Breathing Myocardial T1 Mapping using Inversion-Recovery Radial FLASH and Motion-Resolved Model-Based Reconstruction. Magnetic Resonance in Medicine: DOI: 10.1002/mrm.29521. [1,2]

The algorithms have been integrated into the Berkeley Advanced Reconstruction Toolbox (BART) [3] (commit 3f6ebb12).

The raw files are hosted on ZENODO and must be downloaded first:

Manual download: 
    Part 1: https://doi.org/10.5281/zenodo.5707688
    Part 2: https://doi.org/10.5281/zenodo.7350323

Download via script:
    All files: bash load_all.sh

After downloading, all raw data including ROIs are in the "data" folder.

The other folders contain:

all_phantom.sh scripts, which performs single-slice and motion-resolved model-based image reconstruction for the experimental phantom data sets presented in the paper
all_volunteer.sh scripts, which performs motion-resolved model-based image reconstructions for all volunteer data sets presented in the paper
all_pig.sh scripts, which performs motion-resolved model-based image reconstructions for the experimental pig data set presented in the paper
Figurex/Figurex.sh scripts, which create cfl files for the corresponding Figures and Videos.

The data can be viewed e.g. with 'view'[4] or be loaded into Matlab or Python using the wrappers provided in BART subdirectories './matlab' and './python'.

If you need further help to run the scripts, I am happy to help you: [email protected] / [email protected]
