If you own or operate an MRI scanner you understand how important it is to monitor your system's helium level and cooling performance. You may also know that even with regular checks, things that will drop your helium level dramatically and put you at risk for a magnet quench can still happen. Nights, weekends, even regular office hours between checkups are all times when a parts failure somewhere in your system can send the temperature up and the helium to a boil.
So, if you can't have someone watching your MRI 24 hours a day, what can you do to prevent incidents like this? The answer might be a device called a remote diagnostic unit (RDU). We'll tell you more about the RDU and how it works in the next few paragraphs.
