Electroencephalography (EEG) forward solution computes the electrical potentials over the electrodes that are lying on the scalp surface. Forward solution requires a numerical head model to work on. The head model can be spherical or a realistic one. Accuracy of the forward problem can be improved by using realistic head models. Triangulated realistic head model is an input for the Boundary Element method (BEM) which solves the EEG forward problem. In this paper, a software is introduced which constructs 3-D triangulated realistic head models from the Magnetic Resonance images.
