Dixon-RAVE Matlab Code

Dixon-RAVE Matlab Code

Thomas Benkert

Matlab source code for Dixon-RAVE model-based radial fat/water separation as described in:

Benkert T, Feng L, Sodickson DK, Chandarana H, and Block KT: Free-breathing Volumetric Fat/Water Separation by Combining Radial Sampling, Compressed Sensing, and Parallel Imaging, Magnetic Resonance in Medicine, available here. The preprint can be downloaded here.


The provided Matlab code performs a conventional Dixon-RAVE reconstruction. For implementations of the following extensions, feel free to contact me (thomas.benkert@nyumc.org):

- XD-Dixon-RAVE (motion-resolved reconstruction)

- Motion-weighted Dixon-RAVE (reconstruction with improved motion robustness)

- DCE-Dixon-RAVE (reconstruction for dynamic contrast enhanced measurements)


Results generated with available code:

The source code uses the following external packages:
    - NUFFT toolbox by Jeffrey Fessler
    - Siemens TWIX file reader mapVBVD by Philipp Ehses
    - Fat/water toolbox, contributions by Mariya Doneva and Johan Berglund
