Abstract :
The reconstruction and imaging of complex current density distributions on basis of their magnetic fields in computer simulations and phantom experiments are discussed. Two methods based on linear estimation theory and on the Fourier transformed Maxwell equations in combination with the Whittaker-Shannon sampling theorem are presented. These techniques are used in neuromagnetic brain research and diagnostic applications for noninvasive localizing of active neural areas. Both approaches lead to information on the number, location, and spatial extension of the current generators.<>
