On Sunday August 30, 2020, Dr. Samu Taulu at I-Labs of the University of Washington (Seattle) presented a lecture at the Japan’s Human Brain Mapping. His topic was “A unified and robust spatiotemporal interference suppression method for multichannel MEG and EEG data.” Since his graduate work and then when working at the then-Elekta Neuromag Magnetoencephalography (MEG) division, Dr. Taulu developed two Gold Standards for noise suppression – the Signal Space Separation and the time related tSSS. He is now working at the Physics Department and at I-Labs where his noise suppression software continues to evolve.
This latest effort – named as Denoise 2 – examines and demonstrates the interrelation between the electrical and magnetic fields in medicine, specifically EEG and MEG. However, where his initial work dealt with MEG exclusively, he has now branched out into EEG.
His lecture explained ”the novel EEG-applicable spatiotemporal interference suppression method (Denoise II.)” In his words the goal “is to remove as much of the interference as possible with as little harm to the brain signal as possible. The interference suppression method should be as automatic as possible in order to make it objective and clinically applicable.” Readers with interest may refer to Drs. Taulu and Larson’s article Unified expression of the quasi-static electromagnetic field: Demonstration with MEG and EEG signals. IEEE Transactions on Biomedical Engineering 1–1 (2020).
Sigma3 SP LLC is collaborating with Dr. Taulu to bring that to the physicians in 2021.
