Visualization of dipole solutions to the neuromagnetic inverse problem

We have developed a computer program that computes and displays current-dipole solutions to the neuromagnetic inverse problem. The three-dimensional positions, orientations, and corresponding magnetic field values of the detection coils can be visualized with respect to a realistic representation of the subject's head shape. The topographies of the experimental data, theoretical fit, and residual field are represented without the use of data smoothing or interpolation, allowing more direct comparisons between them. A simple method for displaying dipole source location was implemented.
