Excellent explanation. The discussion of the underlying phenomenon, NMR (nuclear magnetic resonance), brought back memories of grad school. I would frequently forget to leave my wallet at my lab desk and would only remember once I was already next to the NMR spectrometer. My credit card companies and bank probably wondered why I requested so many replacement cards.
I did my PhD in the field of MRI. I wish I had this video back then. Great visualizations without oversimplifying things.
Why are the Jewish corporations corrupting the trailer trash and ghetto's politics?
Oh heck yeah! Just as I get ready to rewatch House M.D.!
Great information on the physics of MRI Senior Field Engineer For over 40 years WELL DONE!
Extreme UV lithography is arguably more complex tech
one of best videos explaining MRI, nice job.
Usually I watch your videos and find a few things that are are interesting, but this piece was fascinating from beginning to end! Truly a marvel of engineering
6:17 Y= R^-2
I wouldn't say that CT scans pale in resolution to MRI since spatial resolution for CT can be better than MRI (from what they tell me). CT can be great for bone visualization
Okay, halfway through the video and my brain hurts. I think MRI’s will just remain “magic machines” to me for the foreseeable future.
Can we do this remotely with pumped phase conjugation (entanglement via distortion correction theory) made by the interference pattern produced with phased array antenna of the proper configuration? This would give us realtime remote MRI given the right frequency and geometry. Film at 11.
This is the most complicated thing in the world.
Good to have it, better not to needed and best not to pay for it.
I thought it was H2O that caused the dipole effect due to the angle of the two hydrogens small charge vs the oxygen's large charge creating a dipole along the central axis of symmetry (between the two hydrogens and through the middle of the oxygen atoms)
MRI is jojo reference (spin)???
This is the gold standard of physics videos.
Fun fact:
For the highest level of education you can choose in the Dutch equivalent of high school, the principles behind this are REQUIRED to be taught and can show up on your exams. I myself was unlucky enough to have this on an exam where I had to manually calculate the voltages and more to achieve a specified gradient slice in an MRI machine, it's absolutely bonkers physics but it does genuinely work really well.
Normally it shows up on your exams with easier examples than MRI's though, but I have gotten a grade for this exact thing. (You'd roughly be 17-18 years old at this time, with 3 years of chemistry/physics under the belt and then another 3 years focusing in on physics)
I’ve had a brain tumor since September of 2019 and I have to get an MRI every 3 months on top of being epileptic.
I have had one every 6 months for the last 28 years
all i got from this is that my phone camera can be used as an mri
I love the way u explained…a big salute
THE TRAMP THAT STOLEN AND SOLD THIS AS SPAWNS GET RICH PLANS THEN PAYED WITH THIS FOOL''s ! THIS WAS FOR THE HUMAN's LEARN THE SPAWN''s OF WHAT IS DEVIL FAMILY OF CRIME''s STEALING TECH FROM THE START YOUR GOING FOR TESTING THAT THE TRADE THEY SOLD YOU ON ! YOU NOT GETTING OF THE EARTH''s GARDEN's OR ANY OTHER 's YOUR TESTED ON THE NEW TECH FROM THE CON's' SPAWN''s SOLD YOUR FAMILY'' GET RICH SCAMMERS PLAN's ON THIS OR ANY OTHER TECH !
Imagine Being the Guy that invented this Crazy machine…
Probably some Patient Died in the early stage.
Wish u included the clip of the office chair getting sucked in like a jet engine, or the stapler possessed by demons haha, always wonder if it can do any damage (other than the guy that forgot to remove his pistol in the room and it shot him)
Why does it look like every comment to this video is written by a bot?
First time I get a video with multiple language tracks. My YouTube is in French, so the French track started when playing this video. This robotic and dead voice is awful. No way I would listen to that whole video with this. Thank you for trying though, this is a cool feature. But the quality is just not enough to be usable.
That whole helium section gave me so much anxiety. We just fill crappy balloons and floats with the stuff and waste so much.
Just wanna say, it's technologist not technician. MRI, CT, and X-Ray all have to get either and two or four year degree. So the proper term is technologist.
I recently (7 months ago) I started working on GE MR and CT scanners. I have great appreciation for these magnificent and complex machines, and it made my day seeing this YT channel than I have watched for years do a great job explaining how the machines I work on every day, work.
But how does a pull 300,000 times stronger than the gravity of earth not rip the iron from your blood?
