Results of 3D MRI image reconstruction for FLAIR contrast using 40 radial spokes. The first and second rows show the prior 3D MRI (first exam) and ground truth of target 3D MRI (second exam) image, where each column demonstrates cross-sectional slices of the 3D volume. The final row shows the reconstructed 3D MRI image by using the proposed NeRP method. For comparison, the second to fourth rows show the reconstruction results of Adjoint NUFFT method, GRFF method [20] and NeRP without using prior embedding as ablative study. The zoom-in red boxes highlight the difference in brain tumor region for comparison.
