Abstract

The source localization principle is an inequality between the means of scalar fields produced by different sources in any linear shift-invariant system. This principle is presented here as a pair of conditions (spatial and temporal) under which a point source produces a greater mean field over finite source-centered regions than all other sources. Biomedical applications involving point optical sources and radioactive sources are discussed.
