MRI systems are invaluable in medical diagnostics, but they depend on liquid helium to maintain their powerful magnetic fields. Without sufficient helium, a magnet quench can occur—leading to downtime, costly repairs, and service interruptions. At TMC, we provide timely and reliable helium fill services to help facilities prevent quenching and maintain operational efficiency.
Why Helium is Critical for MRI Systems
Helium is the lifeblood of an MRI machine. It keeps the superconducting coils cold, allowing the magnetic field necessary for imaging to exist. Without enough helium, the magnet loses its superconducting state, leading to a quench—a sudden loss of the magnetic field that can cause severe damage and require costly recovery efforts.
The Risks of Magnet Quenching
Magnet quenching is the most catastrophic event an MRI system can experience. The consequences include:
- High Recovery Costs: Restoring a quenched magnet can cost over $100,000.
- Operational Downtime: Facilities may face weeks of lost imaging capability.
- Patient Impact: Service delays affect patient scheduling and care quality.
Warning Signs of Low Helium Levels
The good news is that low helium levels provide warning signs before leading to a full quench. Key indicators include:
1. Helium Levels Below 60%
Any MRI system operating below 60% liquid helium is at heightened risk of quenching. Regular monitoring is crucial to maintaining safe levels.
2. Increased Boil-Off Rate
If your system is losing helium at an accelerated rate, it may indicate an issue with the cryogenic system.
3. Temperature Fluctuations
Rising temperatures within the system can indicate insufficient helium levels to keep the magnet stable.
4. System Alarms & Alerts
Most MRI systems have built-in sensors that detect helium shortages and trigger alarms. Ignoring these warnings can lead to serious consequences.
