Retrospective motion estimation for fetal brain MRI
Résumé
Magnetic Resonance Imaging (MRI) is performed on fetus, to study cerebral development. However, the image is affected by child's and mother's motion. Ultra-fast MRI sequences allow to reduce artefact in slices, but motion still occurs between them. We propose a method based on orthogonal slices intersection to correct motion as well as a new solution for outliers removal.
