Among the methods proposed for EPI geometric distortion correction Phase Labeling for Additional Coordinate Encoding (PLACE) has the advantage that it does not require post-processing steps because the correction happens real-time during acquisition. In this study we evaluate the PLACE method quantitatively, first with a finger-tapping task by inducing artificial distortions, and then compared it
