We propose to rigidly mount small, long-lifetime NMR probes to the object in order to concurrently monitor field evolutions in the object frame of reference and perform real-time motion correction without extra scan sequences. In particular, a mere 1ms rephasing gradient is enough to accurately resolve the slice select direction. We show that concurrently monitored acquisitions subject to motion can be reconstructed when calibration-based reconstructions fail and that performing the experiment in the object frame of reference can heavily alleviate image co-registration.
