| Research Abstract |
In equivalent dipole estimation from measured EEG distribution on the scalp, six parameters regarding the position and moment in 3D space are needed for one dipole. We need obtaining a large number of parameters when approximating the EEG distribution by multiple dipoles. Therefore, in this study, we estimated dipole moment from DTI diffusion tensor imagingimagesgave them as additional conditions to the estimation. As a result, our results showed that dipole moment extracted from DTI images was useful to improve an accuracy of dipole estimation.
