The magnetic unit and patient’s seat are located inside the controlled
access area.
Peripheral equipment
The peripheral equipment used inside the controlled access area must be
safe for use in MR environments.
This equipment guarantees that:
☛
no known risks are generated in any MR environment, or when used in
specific conditions
☛
the quality of diagnostic information supplied by the O-scan system is
not altered by peripheral equipment
☛
operation of peripheral equipment is not altered by that of the O-scan
system.
Peripheral equipment labeled as MR safe or MR conditional also
guarantees minimized probability of induced currents caused by
connection of the equipment and the RF transmission coil of the O-scan
system that can generate excessive heating or burns of the patient's skin.
As the patient's skin is conductive, closed conductive loops can form
between the patient and terminals (e.g. ECG electrodes) or cables of the
peripheral equipment, in which induced currents circulate with the risks
mentioned above.
W a r n i n g
Do not allow any persons, who have the conditions and
characteristics for which exposure to the O-scan magnetic and RF
fields is contraindicated, to enter the 0.5 mT restricted area.
W a r n i n g
Users are advised to affix the warning and prohibition labels provided
with the equipment on all of the doors of the O-scan examination
room.
Users are advised to mark the 0.5 mT line on the floor around the
O-scan installation area using the yellow adhesive tape that is
provided with the equipment.
