Subject motion is a major problem in MRI, leading to less diagnostic information in the clinic and lowering data quality in research. Especially at high field, the relatively long scan times applied for high resolution imaging makes motion one of the major challenges. A promising solution is to update the field-of-view in real time based on tracking with MRI-based navigators. Here we show an implementation for prospective motion correction using MRI navigators at 7T. The framework was very flexible, as the navigator and target sequence are simply defined as two different scans, which can be interleaved at any sequence level.
