Five gauss line
WebIn most systems the 5 Gauss field is confined within the scan room, so the fringe field does not affect any area external to the magnet room. The 30 Gauss field demarcates the … WebThe 5 Gauss limit defines the 'safe' level of static magnetic field exposure. The value of the absorbed dose is fixed by the authorities to avoid heating of the patient's tissue and is defined by the specific absorption rate . Leads or wires that are used in the magnet bore during imaging procedures, should not form large-radius wire loops.
