Abstract
A system and method for noiseless measurement of a biomagnetic field uses magnetic field magnitude and gradient measurement at a reference point together with mathematical extrapolation techniques to provide an effectively infinite order gradiometer response from a lower order physical gradiometer. Such a system has the advantages of potentially lower cost, higher accuracy, and easier adjustment and balancing.
