It's science-y enough but I'm definitely not considered a scientist so much as a technologist. I work as a MRI (Magnetic Resonance Imaging) Technologist. Previously a X-Ray Technologist.
My machine does all the science for me but it's a pretty neat concept. Using magnetic gradients and RF pulses at hydrogen protons to acquire accurate digital imaging.
Happy to have you! The science behind MRI is fascinating, and the machines themselves are really cool. Have you ever seen a magnet quench? I don't think they're really supposed to happen during normal operation, but some of the videos I've seen have been rather dramatic.
It is pretty crazy people were able to figure that all out and we are able obtain crazy detailed pictures without radiation.
No I haven't seen it! Hoping to see a controlled quench someday but also hoping to avoid needing to use it in any emergency situations; it'll have to be a damn near life/death situation to hit that button. Very costly decision. I guess there's also a dwindling supply of helium in the world so that could get interesting as time goes on.
Yeah, helium being a finite resource was something that really surprised me when I first learned about it! Better to keep it inside the MRI as much as possible for sure
helium recovery and recycling has come a long way, and the costs of helium are now justifying the extra expense of the hardware, so I think that problem should abate somewhat in the coming years.
