Despite the recent advances in prospective motion correction (PMC) for the correction of rigid body motion, the application of this technique to clinical routine still lacks behind. External tracking and motion correction has been shown to be applicable to a wide range of sequences and to provide sufficient accuracy and precision to improve even data from cooperative volunteers. However, when used in patients, problems such as marker fixation and involuntary skin motion limit the abilities of PMC and can even lead to additional motion artifacts. The aim of this work was to address this last key barrier to help bring PMC to clinical routine.
