# MRI_FISTA - A collection of FISTAs for MRI reconstruction

A library for accelerated fast iterative soft thresholding (FISTA) algorithms tailored for MRI reconstruction.

The repository includes:

 - BARISTA: B1-Based, Adaptive Restart, Iterative Soft-Thresholding

   Algorithm, a fast algorithm tailored for SENSE MRI

 - OM-BARISTA: BARISTA with optimized momentum augmentation

An older version of these scripts is included in the [MIRT](https://web.eecs.umich.edu/~fessler/code/)

### Requirements

 - Requires installation of the [Michigan Image Reconstruction Toolbox (MIRT)](https://web.eecs.umich.edu/~fessler/code/)

 - MATLAB 2011 or higher

### Test Examples

 - see matlab/ir_barista_example.m or matlab/ir_barista_test2.m for test 

   examples
