Monotone FISTA with Variable Acceleration (MFISTA-VA) for Compressed Sensing Magnetic Resonance Imaging

We are making available the codes and test data used for our submitted IEEE-TCI paper “Monotone FISTA with Variable Acceleration for Compressed Sensing Magnetic Resonance Imaging”, authored by Marcelo V. W. Zibetti, Elias S. Helou, Ravinder R. Regatte, and Gabor T. Herman.

The MATLAB codes contain implementation of the proposed MFISTA-VA [1], as well as versions of FISTA [2], MFISTA [3], and OISTA [4], for compressed sensing in magnetic resonance imaging. The codes are comprehensive and ready to apply on low rank, sparse, and low rank plus sparse (L+S) problems [5].

Examples use radial T1rho knee and liver data from NYUMC. Coil sensitivity maps were obtained using ESPIRiT [6].

This package includes NUFFT –Non-Uniform Fast Fourier Transform [7]from MIRT (https://web.eecs.umich.edu/~fessler/code/index.html)
