Maximum entropy method for magnetoencephalography.
Simulations show that the maximum entropy method is a promising technique for image reconstruction in magnetoencephalography. An algorithm based on the work of Skilling and Bryan [1] and an appropriately modified expression for the "entropy" is shown to provide high-quality reconstructions of both isolated and dense distributions of neural current "dipoles", neglecting return currents. In particular the results are substantially superior to those obtained with the well-known minimum norm procedure.
