Reconstructing current distributions from biomagnetic measurements under large external noise disturbances.
External noise fields cause spatially coherent noise in the biomagnetic data measured by a multichannel magnetometer. The authors propose a method of incorporating this spatial coherence into current-density reconstruction. This method can reconstruct current distributions from biomagnetic measurements affected by external noise fields. Computer simulations demonstrate its effectiveness.
