We have developed a novel motion-robust T2-weighted MRI scheme based on single-shot fast spin echo imaging, real-time sensor-based prospective motion tracking, and retrospective super-resolution volume reconstruction. This technique has a simple setup as it requires the attachment of a single miniature magnetic field sensor to the subject head and is platform independent. Quantitative evaluation results obtained for phantom and volunteer subject experiments show the efficacy of the developed technique. This technique enables motion robust imaging, and may enable a reduction in the use of sedation in imaging newborns, children and adults who cannot hold still in the scanner.
