A drive coil and a pickup coil transmit and measure a field passing through the site based upon response of the magnetic nanoparticles, and a processor computes a pain level based upon variations in the field. The pain level can be indexed to an absolute scale that affords more predictability and objectivity in determining true pain level.…","english":"This invention provides a non-invasive system for measuring pain level in a body at a site containing a predetermined concentration of magnetic nanoparticles.
