The Berkeley Advanced Reconstruction Toolbox (BART) toolbox is a free and open-source image-reconstruction framework for Computational Magnetic Resonance Imaging developed by the research groups of Martin Uecker (Graz University of Technology), Jon Tamir (UT Austin), and Michael Lustig (UC Berkeley). It consists of a programming library and a toolbox of command-line programs. The library provides common operations on multi-dimensional arrays, Fourier and wavelet transforms, as well as generic implementations of iterative optimization algorithms. The command-line tools provide direct access to basic operations on multi-dimensional arrays as well as efficient implementations of many calibration and reconstruction algorithms for parallel imaging and compressed sensing.

Quick Example

Perform ESPIRiT calibration and image reconstruction with l1-wavelet regularization:

 $ bart ecalib kspace sensitivities
 $ bart pics -l1 -r0.001 kspace sensitivities image_out

A python-based image viewer ( which can read the BART data format is included in the source repository.

An image viewer for Linux and Mac OS X can be found here.
