This work shows a comparison of prospective motion correction using NMR field probes and an optical tracking system in a phantom with induced motion as well as in an initial in vivo experiment. Tracking results for both systems were recorded concurrently to compare the motion estimates. The prospectively corrected images of a moving phantom and a moving human subject show a comparable correction ability for both systems. However, the lower precision of the field probe based system might prevent an application in highest-resolution imaging.
