How MRI Scanners are Made | How It's Made | Science Channel

I understand the basics of how an MRI machine works but when I watch a show like this I still can’t comprehend how any person was able to come up with this idea and then somehow engineer it. It’s mind blowing.

The gradient coil’s function is to enable the scanner to tell from where exactly inside the machine, among the trillions and trillions of hydrogen atoms inside the human body, did a return signal originate from. Being able to do this is an incredible scientific feat and the way it actually works has to be one of the cleverest inventions of the 20th century. So clever in fact, that Paul Lauterbur, who invented the concept, received the Nobel prize for it.

Great jobs for the physicists, mathematicians, engineers, and programmers in designing these.

The basic physics of what goes on in the MRI process were stumbled upon during radar development in WW2. There were unexplained atmospheric losses of the radar beam that later were discovered to be caused by nuclear quadrupole resonance occurring in the nucleus of nitrogen molecules of the atmosphere. Initially the MRI was called NMRI but (N)uclear was dropped during the cold war, and nuclear weapons fears. The magnetic resonance imaging technology is also used in illicit drug and explosives detection. Very cool stuff.

As an MR tech this is an excellent video…it took me years and many technical manuals and chats with field engineers to under the extreme level of engineering needed to build these machines

[WolfmanDude]

This is my favorite episode of this show yet! There is always something so mysterious about radio frequency electronics like this. Almost like magic that really works. I only wish they showed the construction of the superconducting magnet.

[AmericaVoice]

I am just in awe of how humans can design and use these resources and technology! How many lives has these saves every minute. This includes CT scans and X-rays!

[marktime]

I'm an engineer for these, and this explanation was quite well done. However, I'd like to point out that the actual part that becomes the magnet is not shown nor discussed. The cryostat is shown, but the niobium alloy windings which are housed inside of the cryostat are what becomes superconductive at 4 degrees K while immersed in the liquid helium bath.

Great vid... I had a MRI couple of months ago. Like an EDM concert but the beat never dropped

[elcanol]

This is a great tool that gives quality images without exposing you to harmful ionizing radiation, but it's not for the faint of heart, specially for people with anxiety. I had a full lumbar spine MRI that lasted for 2 hours. Being inside one of these tight chambers, with loud pulsing noises, while staying as still as possible for 2 hours, is nothing short of a great feat. Still, this is a life saving machine, truly amazing.

This video lets you appreciate not only how the Machine works but also how it was Built. 😊

[begotten]

Since 2006 October 29 MRI brain cancer/GBM survivor and counting, 17 years years and counting. Thank you explaining the MRI how it’s going. Thank you 🙏👏

[Elmatador]

Incredible show of human ingenuity. So many parts to this!

[s-w]

I can't believe the guy spray painting isn't wearing a mask.

[koriw]

What a fascinating documentary! I have never known how all the bells and whistles work on an MRI machine, though I always wanted to; I've certainly been in enough of them to have stock options...

[xochj]

This is the best "How It's Made" I've ever seen!

[clumsycolours]

Not sure why this was in my recommended, but curiosity got the better of me and that was fascinating as!!

[hishamabdulmogny]

l love to learn how things are made .... it's beautiful.

[spiritman-emqr]

There's nothing quite like building a $3M gadget in a $96 garage.

[AluminumOxide]

Anyone wonder how the inner magnet itself is assembled or what’s it made of before starting with the aluminium magnet casing? It’s a company proprietary secret.
