Abstract :
A multidipole searching technique using a moving dipole concept is proposed for magnetoencephalography (MEG) source localization. The proposed method can be a promising method to resolve a critical disadvantage of conventional equivalent current dipole (ECD) method-the number of current dipoles should be given a priori. From several simulation results, the accuracy and effectiveness of the method will be verified.
