Here, we present a novel approach of utilizing Boundary-Based Registration for realigning submillimetre 7T fMRI time series. We collected fMRI data from 6 human participants and processed the data using either standard rigid body realignment using SPM or our BBR realignment method. We compared the two pre-processed datasets with multiple metrics (tSNR, fCNR and percentage of variance explained by the model) and show that realigning using BBR consistently outperforms conventional methods.
