Abstract
Apparatus, systems and processes for detection of objects representing possible projectile hazards in areas of high magnetic fields such as those potentially hazardous ferrous objects which may be moved within the region of forceful magnetic attraction by magnetic resonance imaging (MRI) scanners. The systems and process may include multiple magnetic field sensors and multiple time of flight sensors positioned around a passageway. The time of flight sensors may facilitate determination of movement (e.g., speed and/or direction) of the potentially hazardous ferrous object to provide enhanced accuracy of threat detection.
