1. A method for imaging electromagnetically radiating sources in a body, comprising: sensing electromagnetic fields produced by the sources at a plurality of distinct remote locations to produce source field data corresponding to said locations; solving the inverse problem using said data to obtain a first image of the sources at a first resolution; imaging the sources with an independent imaging method to produce a second image of the sources at a second resolution; and combining the images to produce an enhanced image at a third resolution that is greater than the first and second resolution.
