Effect of head shape variations in magnetoencephalography

We propose a method for evaluating the effects of head shape variations on the MEG forward and inverse problems. We use this method to study the effect of head shape variability among different individuals. We propose a random shape head model and use the Stochastic Finite Elements Method to solve the forward problem. We also study the effect of the random head model when solving the inverse problem, which is found to be of the same order as the effect of the electronic noise in the measurements.
