Holy shit, they pulled the emergency release on one of those MRI machines. I think that adds a zero or two to the cost of bringing back online.

even if it was quenched the right way: downtime, helium, restarting the entire thing would also cost pretty penny, and maybe replacement of damaged magnet too if that’s what they did

Yeah, that liquid helium and the MRI down time are super expensive

Yeah, quenching the machine makes bringing it back online $200k+ depending on the system

I’m just an XRay tech. But I would expect at least one whole day, for a pair of engineers to get it running again and re-certified. $20-50K for their time, plus missed revenue from the lost day. Best case could total $100K easy. Way more, if the damage is more than cosmetic.

You’re not counting the materials costs. I doubt that medical grade helium is cheap.

True. I don’t know how much that is. But liquid helium shouldn’t be “medical grade” really. It’s just a coolant for the superconducting magnets, same as any industrial use.

Yeah, I think I remember something like 10-20k to refill the cooling on an MRI, and that is just topping it off as some is slowly lost. The helium is just used to cool it. Helium is helium, so no such thing as medical vs not. The cost to repair this thing is going to be absurd. They are making better machines now have little to no loss, but I don’t think those are super prevalent yet.

More than a day. Ramping can take multiple days, then it has to be conpletely recalibrated and shimmed.

Probably need a new magnet, quenching can melt those puppies. Lot of energy stored in that field.
