This repository contains a PyTorch implementation of Nu-FF for 2D and 3D. Our implementation his deferential according to the coordinates of the measurements, meaning, when using the transform in GD based optimization methods you can update the coordinates of the measurements according to the loss optimization. We used Sigpy as base for our implementation.
To understant the use of pytorch-nufft we addvise to run the example script.
python nufft-test.py
python nufft-test_3d.py
