A higher-order concurrent field monitoring setup is introduced for routine head MRI. It enables the tracking of dynamic field evolution up to 3rd order concurrently with data acquisition. This is particularly important for non-reproducible field contributions, e.g. due to magnet heating, breathing or external fields. The field information allows for the correction of image artifacts at the reconstruction stage.
