These scripts reproduce the experiments described in the article:

Rosenzweig S, Scholand N, Holme HCM, Uecker M.
Cardiac and Respiratory Self-Gating in Radial MRI using an Adapted Singular Spectrum Analysis (SSA-FARY).
IEEE Trans Med Imag 2020, Early Access, DOI: 10.1109/TMI.2020.2985994 [1,2]

The algorithms have been integrated into the Berkeley Advanced Reconstruction Toolbox (BART) [3] (commit 737082541c).

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

• Manual download: https://zenodo.org/record/3822451
• Download via script: Run the download script in the ./data folder.
  • All files: bash load_all.sh
  • Individual files: bash load.sh 3822451 <FILENAME> . ( without file extension. Then extract the *.tgz)
• Note: The data must be stored in the ./data folder

The other folders contain:

• run.sh scripts, which perfoms the image reconstruction
• plot.sh scripts, which create the Figures
• makemovie.sh scripts, which create the movie files
• some *.py scripts for plotting tasks
• and a results folder, with images and movies that serve as reference

To run the scripts GNU Bash [4] is required.

The data can be viewed e.g. with 'view'[5] or be loaded into Matlab or Python using the wrappers provided in BART subdirectories './matlab' and './python'

To reproduce the plots and figures python3 [6], the 'cfl2png' command from _view [5], and 'convert' from imagemagick [7] and the Linux Biolinum font [8] are required. The font can be downloaded by running the get_font.sh script in the utils folder. To create the movies ffmpeg [9] is used.

Please note that BART with GPU support is required. Running all scripts will take more than 24 hours, even on a multi-core compute system!

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