In order to characterize and optimize gridding reconstruction of 3D radial hyperpolarized (HP) 129Xe MRI, we developed a flexible, open source reconstruction software package in MATLAB. The code supports N-Dimensional gridding-based reconstruction of Non-Cartesian MRI data. The code requires only 2 inputs: the measured k-space data and trajectories. The reconstruction framework then constructs a sparse system matrix that can be used to iteratively reconstruct data. A variety of reconstruction parameters can be used to tune the image quality of the output reconstruction. For further details regarding usage and capabilities, see the README that is packaged with the code download.
