Motion artefacts generated by our augmentation model as a result of rotation of the head forwards and backwards around the coronal axis, simulating patient nodding motion. Changing artefact appearance due to changing the time during acquisition at which the movement occurs, later in the k-space scan trajectory from left to right, therefore retaining more lower spatial frequencies. Best viewed zoomed in on digital copy.
