Participants should be under supervision of mr personnel at all times in this zone. Due to the powerful magnetic field used by the mri scanner, many magnetic resonance imaging (mri) facilities and hospitals restrict access to the mr suite by establishing four conceptual zones around the mri scanner. To achieve this, conceptual zones have been established within the scanner’s general perimeter. Participants are greeted and screened in this zone and are not free to move through zone ii.
