Registration of EEG to MRI is an effective way to obtain both high spatial and high temporal resolutions in functional brain imaging.There are two common methods in the registration:fiducial points based matching and surface based matching.The matching based on fiducial points has the difficulties in locating and measuring of fiducial points accurately.Meanwhile
in surface matching
the scalp must be scanned by a high spatial resolution equipment.The aim of this study is to investigate a weighted combination method using electrodes and fiducial points.Simulation results show the effectiveness of the new method.Also
the new weighted combination method has better registration accuracy than that of fiducial points or surface matching using electrodes respectively.
