Performance of the SOZ localization using the DSI method (orange bar) in comparison with the SOZ localization by applying source imaging directly on raw EEG instant by instant (blue bar). (a) The mean and standard deviation of the volume overlapping between the estimated SOZs (60% threshold) and surgically resected regions/SPECT foci in the 17 seizures. (b) Mean and standard deviation of the AUC index derived from ROC analysis. A higher AUC index in the range of [0, 1] implies greater localization accuracy.
