Abstract :
The localization ability of SQUID (superconducting quantum interference device) planar gradiometers for biomagnetic applications has been investigated. A linear planar superconducting-wire gradiometer was constructed and tested. Localization tests were performed both on a current dipole model and on human subjects. It is shown that the accuracy of localization results was not significantly affected by the use of the planar configuration
