- Опубликовано: 29 сен 2024
- Paul Callaghan gives an introduction to NMR and MRI. Paul uses a mechanical wheel to illustrate the key concepts of precession, relaxation, and resonance. First in a 10 episode series produced by Magritek Ltd. see www.magritek.co... for more
This is an amazing video where such a complex concept is taught in such simple terms. Prof. Callaghan you are a star.
Dr. Callaghan;
You are the world's greatest lecturer! Can't wait to see the rest of your videos!
Thank you for the demonstration as I am taking MRI this Spring 2013.
Excellent Paul..thanks for sharing this
Dr. Callaghan the best!
Beautiful explanation...thanks a lot for the video!!
The best and most easily understood of all the numerous MRI lectures. Thank you Sir Paul Callaghan.
Thank you so Much Professor for nice illustration
truly helpful
thank you
wow, where have you been all semester?
wish that i had seen this as an undergrad. I struggled to understand nmr at the time.
x1000 thumbs up
You sir... are a genius!
Thank you SO MUCH Dr. Callaghan! I have been struggling to understand the concepts behind NMR for a while now and have not been able to find a simple, clear explanation of the basic physics behind NMR until now. Your videos are amazing and make a very complicated and difficult to understand concept much easier to grasp!
It is really the best online videos series of NMR I´ve watched, congratulations.
Finally I´ve understood relaxation times: T1, T2 and T2*!
@5:19 A beautiful explanation easy to understand and remember.
@ 6:10 (he left out) the stimulus field is very small compared to strength of the static field.
A very didactic demonstration, thanks for sharing your knowledge!
My goodness! After hours of trying to grapple with MRI, this is so simple to understand because it's explained so well.
Thanks a lot Paul, you are a very good teacher.
videos like this make youtube so great.
Greetings from Germany
THANK YOU SO MUCH!!! That was a great and clear explanation of NMR.
Thank you so much! My textbook makes this so much harder to understand.
Thank you so much for this genius explanation!!! OMG that explains A LOT!
Thanks a lot ,very good demonstration.
RIP Paul Callaghan. Thank you for these videos, great help!
Thanks a lot. I am trying to understand NMR just because it fascinated me, and i think i have the initial grasp
I'm so glad I stumbled in to you and your videos. I'm an MRI Tech and this video was so easy to grasp and understand. I understand how it works but the way you explained and demonstrated precession and resonance is so easy to understand. Thank you and will view the rest of the videos.
I was just looking for more videos about NMR after viewing this wonderful series when I saw that Sir Paul Callaghan had died of cancer a few months ago. What a shame. This amazing man has helped me, and from the looks of things, about a hundred thousand other people all around the world understand NMR much better than I had before. I have no doubt that he will help millions more in the future. RIP Dr. Callaghan.
Oh thanks a lot! I'll try to translate it in russian and retell&demonstrate it to my friends.
great!
Awesome sir...the concept u have explained so nicely by demonstrating with the help of wheels, probe etc are amazing.. these concepts are very difficult to get by going through the books...almost i have watched all your videos...each professor should demonstrate the same way......!!!! thank you so much sir...!!! :)
I'm going to do my reexam on Friday, so I'm going to watch all your video's. :) Thus far they are very helpful. I've seen yours on T1 and T2 and T2* before, it was the only explanation that made me understand the concepts!
This is a beautiful presentation. Excellent explanation of precession and resonance.
excellant demostration
You made the concepts seem simple
Thank You
oh, thank you, i'm studying for my medical imaging exam this morning. this video helped a lot. i understood the basics. great job
Genius!!!!! thanks a lot!!!!!
Thanks a lot Dr Paul Callaghan for this explanation.. :D
Thank you so much for uploading this, it really helps me to understand NMR and MRI.
That was truly excellent and very easy to follow! Thank you very much!
Thank you for your explanation
thank you doc
amazing, thank you for making these videos!
Thank you for the wonderful lecture!
Thanks so much, this is great :)
Excellent and great video
Very helpful! Thank you
so helpful for learning MRI basics!
Truly excellent
