Effects of head modeling errors on the spatial frequency representation of MEG
Wan-Jin Yeo, Eric Larson, Joonas Iivanainen +5
Optically-pumped magnetometers (OPM) -- next-generation magnetoencephalography (MEG) sensors -- may be placed directly on the head, unlike the more commonly used superconducting qu…
Towards analytical calculation of the magnetic flux measured by magnetometers
Wan-Jin Yeo, Yao-Rui Yeo, Samu Taulu
This paper reviews magnetic flux signal calculations through pick-up loops using vector spherical harmonic expansion under the quasi-static approximation, and presents a near-analy…
Effcient magnetometer sensor array selection for signal reconstruction and brain source localization
Wan-Jin Yeo, Samu Taulu, J. Nathan Kutz
Magnetoencephalography (MEG) is a noninvasive method for measuring magnetic flux signals caused by brain activity using sensor arrays located on or above the scalp. A common strate…
Calibration and localization of optically pumped magnetometers using electromagnetic coils
Joonas Iivanainen, Amir Borna, Rasmus Zetter +6
In this paper, we propose a method to estimate the position, orientation and gain of a magnetic field sensor using a set of (large) electromagnetic coils. We apply the method for c…
