This repo contains code for Refining DL reconstruction via null-space kernel.

As can be seen in the Figure, (a) is undersampled MRI reconstruction from UNN (Unrolled Neural Network) and (b) is the proposed refinement process.

By utilizing a null-space kernel, we can correct for errors in Deep Learning's kspace estimates and refine reconstruction.

Please refer to demo.ipynb for demonstration of running the code and examples.
