Abstract

This paper presents a method to locate EEG dipoles (recorded using the 10-20 International System of Electrode Placement) on the patient´s MRI. The 10-20 anatomical landmarks are identified on the MRI with the help of a surface rendering and the dipole position provided by the BESA software is transferred into MRI coordinates. Different to other methods, no external markers are necessary. The results on eight treatment refractory epileptic patients show that this approach improves the information provided by the BESA program, locating the dipole on its anatomical source
