A novel method for extracting interictal epileptiform discharges in multi-channel MEG: Use of fractional type of blind source separation

摘要

Objective: Visual inspection of interictal epileptiform discharges (IEDs) in multi-channel MEG requires a time-consuming evaluation process and often leads to inconsistent results due to variability of IED waveforms. Here, we propose a novel extraction method for IEDs using a T/k type of blind source separation (BSST/k).
