These scripts reproduce the experiments described in the article:

Xiaoqing Wang, Sebastian Rosenzweig, Nick Scholand, H.Christian M.Holme, Martin Uecker.
Model-Based Reconstruction for Simultaneous Multi-Slice T1 Mapping using Single-Shot Inversion-Recovery Radial FLASH.
Magnetic Resonance in Medicine: DOI: 10.1002/mrm.28497.[1,2]

The algorithms have been integrated into the Berkeley Advanced Reconstruction Toolbox (BART) [3] (version 0.7.00).

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

• Manual download: https://zenodo.org/record/3969809

• Download via script:

  • All files: bash load_all.sh
  • Individual files: bash load.sh 3969809 <FILENAME>. ( without file extension. Then extract the *.tgz)

The other folders contain:

• all.sh scripts, which perfoms model-based image reconstructions for all data sets presented in the paper
• run_xx.sh scripts, which performs model-based image reconstruction for a specific data set
• Figurex/Figx.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'.

Running all scripts will take several days (a single data set may take a few hours) on a multi-core computer system!

If you need further help to run the scripts, I am happy to help you: xiaoqing.wang@med.uni-goettingen.de.
