Tracking head mounted NMR markers enables to carry out prospective motion correction for brain MRI. In this work, a NMR marker tracking method that facilitates easy deployment is characterized with respect to tracking reliability in the presence of hardware drift and other imperfections. The method is then applied to a high-resolution in-vivo scan with long scan duration.
