NUFFT-Torch

Python-based differentiable NUFFT package optimized for multi-echo and model-based MRI.

Getting Started

Installation

NUFFT-Torch can be installed using pip:

1. Clone the repo

git clone git@github.com:FiRMLAB-Pisa/nufft-torch.git

2. Navigate to the repository root folder and install using pip:

 pip install -e .

Usage

Check basic_example.py in the benchmarkfolder for a simple usage example (Coming Soon: proper documentation and examples.)

Other Packages

The package is inspired by:

1. torchkbnufft (Pytorch implementation of Michigan Image Reconstruction Toolbox NUFFT)
2. SigPy (for Numpy arrays, Numba (for CPU) and CuPy (for GPU) backends)
3. PyNUFFT (for Numpy, also has PyCUDA/PyOpenCL backends)
