Abstract:Motion artifact is a serious problem to MRI diagnosis and analysis due to periodic motion or patient motion during the image acquisition. A metric-based method, EXTRACT, used the information by using extrapolation of the k-space data and a metric based on correlation between the extrapolated k-space data and the motion corrupted k-space data. In this paper, we propose to use the finite support technique in conjunction with the generalized series in the spectral extrapolation to determine the motion that causes… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
