Abstract

In this work we estimate magnetic sources in the cortical region. The region for estimation is limited to the surface of the cortex. Considering this limitation, the cortex is extracted from MR images. We assume that the points on the extracted cortex are current dipoles. All the acquired points are considered as candidate sources. We perform the estimation by means of the MUSIC method which is applied to the limited region. In the MUSIC method, the measured magnetic field data is divided into two subspaces, the signal subspace and the noise subspace. The MDL criterion is used for this division.
