Deventer Hospital - Quench pipe MRI-Linac
When an MRI scanner has to make an emergency stop, a process called quenching is activated. In this process a sudden loss of absolute zero temperature is activated in the magnet coils. This will cease the coils to be super conducting and they become resistive instead, thus eliminating the magnetic field.
During this proces helium will escape from the cryogen bath extremely rapidly, and since helium can reach temperatures around -269 °C a special quench pipe ducting system has to be constructed to guide the gasses safely outside.
- Ensure that the fire suppression piping system meets all government regulations
- Create a ducting system strong enough to accommodate an MRI emergency shutdown
- The duct system must also be able to expand significantly
The design, manufacture and installation of a system that is both strong enough and flexible enough to handle an MRI emergency shutdown.
