2.2.1.1 Controlled Access Area
The Controlled Access Area is the three-dimensional area in which the magnetic field
strength is 0.5 mT and higher. It is defined by the 0.5 mT magnetic stray field line of the
magnet. The contour maps of the magnetic stray field are provided in the System Owner
Manual.
System owner or authorized personnel must ensure that individuals entering the Controlled
Access Area must put down all loose ferromagnetic objects and must be questioned about
their medical history (e. g. with respect to pace-makers, surgical implants, metal splinters,
etc.).
Individuals with implants (e.g. cardiac pacemakers, clips, prostheses, etc.) are not allowed to
enter the Controlled Access Area and pass beyond this 0.5 mT contour line.
It is the responsibility of the system owner to inform all users about applicable national and
local regulations and occupational standards.
WARNING
Risk of personal injury or death due to effects originating from strong
magnetic fields.
Entering the Controlled Access Area bears various risks that can lead to serious injuries.
People with medical implants or pacemakers must not enter the Controlled Access Area.
u
Refuse and prevent actively people carrying medical implants entering the Controlled
Access Area.
u
Refuse and prevent actively non-authorized and or non-trained personnel entering the
Controlled Access Area. Inform visitors on the potential risk originating from the high
magnetic field. Do not leave visitors unattended.
u
Be familiar with the extension of the 0.5 and 3 mT region within the Controlled Access
Area.
u
Always reflect and be aware of the potential risks when entering the Controlled Access
Area. Accidents occur often by being unthoughtful or careless during routine work in the
Controlled Access Area.
u
It is good practice to establish a standard procedure when entering the Controlled
Access Area and depose all personal accessories outside that might be affected or
become dangerous projectiles.
WARNING
Risk of personal injury or death
The magnetic field of the superconducting magnet remains on even when the MR instrument
is powered off.
u
All safety measures associated with the Controlled Access Area have to be observed
even when the MR instrument is powered off.
