We propose a statistical learning approach to enhance contrast in EIT imaging of the brain. The conductivity is modelled as a combination of two unknowns, spatially distributed background and the skull layer. The discrepancy between the forward models with and without the skull layer is treated as a modelling error which is handled by the Bayesian approximation error approach. The approach is evaluated with simulations and phantom data.
