A standardized boundary element method (BEM) volume conductor model was developed using averaged magnetic resonance imaging (MRI) data from the Montreal Neurological Institute. This model provides a realistic representation of the head for source reconstruction in electroencephalography (EEG). The model consists of three compartments: skin, skull, and brain, with 4770 nodes. The electrode positions were transformed into the model's coordinate system using fiducials and a scaling factor. The potential values at the transformed electrode positions were calculated using linear interpolation from the stored transfer matrix of the outer BEM compartment. The best fit dipole results were then transformed back to the original coordinate system. The standardized BEM model was compared to spherical shell models and individual BEM models derived from individual MRI data. The results showed that the standardized BEM model provided significantly better localization accuracy, especially in basal brain areas such as the temporal lobe. The spherical shell model resulted in mislocation errors in these areas. The standardized BEM model was applied to averaged and unaveraged epileptic spike data from seven patients, and the results were compared to those obtained using spherical shell and individual BEM models. The standardized and individualized BEM models were found to be comparable in terms of accuracy. The computational performance of the standardized BEM model was evaluated, and it was found to be about 60 times slower than using analytical spherical models. However, this computational effort is still acceptable for most applications. The use of a standardized BEM model offers an easier and faster access to realistically shaped volume conductor models compared to deriving specific models from individual 3D MRI data. This approach is particularly useful in clinical settings where obtaining high-quality MRI data for individual patients is not always feasible. The results suggest that standardized BEM models can be used as a substitute for spherical head models in clinical source modeling, especially when individualized models are not available or practical.A standardized boundary element method (BEM) volume conductor model was developed using averaged magnetic resonance imaging (MRI) data from the Montreal Neurological Institute.
