Abstract
A method to screen individuals specifically for paramagnetic or ferromagnetic objects they may be carrying or wearing, before they enter the high-field region of an MRI suite. The device used comprises either a screening portal or a compact, hand-held magnetic gradiometer and its electronics. The method places all of the sensor arrays in close proximity to all parts of a subject's body, for screening purposes.
