Image comparison among low resolution VIPR reconstructed using gridding and zero-filling technique (a), HYPR CE (b), and high resolution CE image (c) from the same aneurysm patient. Line profiles across the aneurysm as shown in (c) were compared in (d). The aneurysm lumen from HYPR CE matches that from the high resolution CE image very well, where the VIPR shows significant blurring compared to the high resolution CE image.
