The simultaneous acquisition of non-invasive human brain
imaging techniques, including EEG, PET and fMRI can give
insights into the connections between neuronal activity,
receptor occupancy and function. However, standard
dense-array EEG caps can cause artifacts in both MR and
PET images, making simultaneous imaging a challenge. We
thus designed a 256-electrode EEG cap based on
conductive polymers, and demonstrate its superior
performance in RF invisibility and reduced photon
attenuation for the use of simultaneous EEG-PET/MR
imaging.
