Working principle of the MRI Scanner service:
The main magnetic field of the imaging device is generated by a superconducting electromagnet in which an electric current is circulated. No presence of metal is permitted in the MRI room. Once the current flows through the coil, it will flow without dissipating as it suffers no resistance.
The power that initiated the current can then be disconnected: the current and the magnetic field that results will continue as long as the temperature is kept sufficiently low thanks to liquid helium.
The risk with Helium:
Helium is odourless, non-flammable and non-toxic, but the patient should be removed at once from the examination room since oxygen depletion provides a risk of asphyxiation, and there is temperature danger from the very cold gas.
If the evolution of the escaping gas and depletion of oxygen has increased the pressure in the room so much, as, to prevent the opening, to the examination room, the window between the scan room and the control area should be broken to release the pressure.
Systems should be fitted with a venting system, which expels the escaping gas to the outside air. If this system fails, cold helium gas may spread throughout the patient area.

ATA SOLUTIONS FOR MRI AND SCANNER ROOM:
• Air Conditioning of Technical Room is part of the solution in temperature and relative humidity with the CLIMA PROCESS AHU.
• Air Conditioning of IRM equipment room itself is part of the system with the TOP TOP AHU.
Advantages:
– Avoid Risk of Asphyxia in Case of Helium Gas Leakage.
– Avoid Over-Pressure link to the Helium Leakage.
– Avoid Risk of Asphyxia in Case of Helium Gas Leakage.
– Avoid Over-Pressure link to the Helium Leakage.
• Cooling the Heart of IRM system with cooling Water or city water supply network in case of electrical power failure – with the ATA Hydraulic set.
Advantages:
– Automatic switch over system from chilled water to city water supply in case of power failure.
– Avoid technical shutt down, extremely costly for client and technically complicated.
– Tele-Monitoring of the System.
