Abstract

Motion is one of the most common artefacts in MR imaging which reduces the image’s diagnostic capabilities. Despite this, a mathematical post-processing method for motion correction is yet to be established. In this study, the Gegenbauer reconstruction method is used in resolving MRI motion artifacts. Shepp-Logan phantoms were used in assessing the applicability of the method. The Gegenbauer method’s performance was compared with the performance of Fourier reconstruction, a common method used in MRI data processing. Results show that Gegenbauer reconstruction performs better than the Fourier method in reconstructing motion-affected images, however, it fails to fully remove the motion artifacts. The results suggest the possibility of using the Gegenbauer reconstruction method as a viable post-processing tool for MR motion correction.
