These scripts reproduce the experiments described in the article:

Rosenzweig S, Holme HCM, Uecker M, Simple Auto-Calibrated Gradient Delay Estimation From Few Spokes Using Radial Intersections (RING), Magn. Reson. Med. 2018, 10.1002/mrm.27506. [1,2]

For the current version of these scripts, a version of the Berkeley Advanced Reconstruction Toolbox (BART) [3] (commit 480509c4 or newer) is needed. Older versions of these scripts (found in the git history) work with BART versions starting from v0.4.03.

In each folder the *.sh shell-scripts must be started. These scripts require BART [3].

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'

For the plots python [5] is used.

Total runtime for all scripts is approximately 1 hour.

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