SigPy

with Chris Sandino, Sri Koundinyan, Ke Wang, and Miki Lustig

SigPy is a Python package for signal processing, with emphasis on iterative methods. It is built to operate directly on NumPy arrays on CPU and CuPy arrays on GPU. SigPy provides several domain-specific submodules: sigpy.plot for multi-dimensional array plotting, sigpy.mri for MRI iterative reconstruction, and sigpy.learn for machine learning.


mridata.org

with Gaby Nahum, Shahab Amin, Shreyas Vasanawala, and Miki Lustig

mridata.org is an open platform for researchers to share MRI raw k-space datasets. This web site provides open datasets to researchers who desire to contribute to a community of reproducible research, where they can test and validate their algorithms against known undersampled acquisitions.


BART

with Martin Uecker (main developer), Jon Tamir, Miki Lustig and others

The Berkeley Advanced Reconstruction Toolbox (BART) is a free and open-source image-reconstruction framework for computational MRI developed by the research groups of Martin Uecker and Michael Lustig. I was a core developer for many years til 2017.
