Abstract:PurposeSubject movement during the MR examination is inevitable and causes not only image artifacts but also deteriorates the homogeneity of the main magnetic field (B0), which is a prerequisite for high quality data. Thus, characterization of changes to B0, for example induced by patient movement, is important for MR applications that are prone to B0 inhomogeneities.MethodsWe propose a deep learning based method to predict such changes within the brain from the change of the head position to facilitate retros… Show more
