Abstract: It is commonly accepted that there is no significant gain in computing precisely the center of radial distortion (CoD). Indeed, practitioners take the center of the image (CI) and the principal point (PP) as proxies… read more here.

Abstract: Background Center-out radial sampling of k-space in magnetic resonance imaging employs a different direction for each readout. Off-resonance artifacts (including those produced by chemical shift between water and fat) found with this type of sampling… read more here.
