How was that allowed?
...while the machine was still working? And isn't that the job of the technician anyway?
Those machines have a kill-switch for a reason.
I call this BS or a very incompetent technician.
Plus a Darwin award for the guy.
Couple things:
The magnet is ALWAYS on.
The "kill switch" takes about five minutes to actually deactivate the magnet and it costs about thirty grand in helium every time you push it.
Isn't it an electomagnet?
Oh, right, i forgot human lives have a price in the US.
It's not an electromagnet, it's a superconducting magnet. And turning it immediately off makes it melt.
It's both! MRI magnets are electromagnets that are cooled down to 4 Kelvin using liquid helium. Once they reach those low temperatures, they become superconducting. This way, the magnet isn't gobbling up tons of electricity to stay at the desired field strength. Instead, the liquid helium needs to be replenished occasionally to keep it at superconducting temperature. Source: I work with MRI scanners.
TIL, thanks
