T2* weighted imaging, which is particularly relevant in studying dementia, is prompt to artefacts caused by subject-induced field fluctuation and head motion. Solutions have been proposed to tackle each of these issues separately. In this work we propose to address the two issues concurrently with feedback field control and marker-based prospective motion correction based on gradient-tones. We demonstrate the effectiveness of the combination in the scenario of limb motion.
