Reconstruction results of the proposed method compared to GRASP and XD-GRASP reconstruction for human abdomen Dataset-1 at AF = 8 with 11 temporal frames having 96 radial spokes/frame.

Reconstruction results of the proposed method compared to GRASP and XD-GRASP reconstruction for human abdomen Dataset-1 at AF = 8 with 11 temporal frames having 96 radial spokes/frame.

<p>The proposed method improved overall image quality, providing better vessel clarity than the GRASP and XD-GRASP reconstructed images shown by arrows.</p>
