MRI Machine - Main, Gradient and RF Coils/ Magnets | MRI Physics Course | Radiology Physics Course#2

Michael, thank you a lot for the great channel! Could you please answer the question? What's the reason for using gradient coils? What the main goal for magnetic field strength heterogeneity? Or it is explained in next videos:) Thank you again!

Where can I get the Short questions sir? And thank you so much for explaining it so easily with pictures.

Why are you just so amazing! How can we support you doing this for freee?

Awesome, the animations are fantastic, and also you include enough details that might be easily overlooked in some other tutorials. Thank you !

Amazing how great you are explaining all of this! I'm a MRI technician and this week Siemens workers changed our gradient coil which was broken. They explained to me the shimming process and even showed me the pieces of metal they used for it. But you made it all so much clearer! Will be watching all of your videos for sure!

very helpful! Thank you.

beautiful.
i love how you explain and make things easy for someone who does not have a physics brain.
god bless you

YOU ARE A GREAT TEACHER.
I LEARNED A LOT AND REGISTERED TO YOUR CHANNEL.
PLEASE DO MORE OF THESE VIDEOS AND EXPLAIN IN A WAY TO MAKE IT EASY FOR US TO UNDERSTAND.
GOD BLESS YOU.

such a perfect video. I really appreciate your knowledge and also your ability to explain these difficult concept in a clear way. thank you so much you made this lesson easy for me.

with regard to spatial gradient magnetic field of x and y direction, is the gradient magnetic field directed to z axis and its magnitude is changing along x and y axis?

You are brilliant !

the best explanation, thanks a lot

Dear Dr. Nel,
Out of curiosity, did you mean "homogenous" or "homogeneous" when referring to the ideal world magnetic field? Apparently, the pair is a loved example of some essayists and grammarists. Both meanings might fit although homogeneous is probably the right one 🤓
Thanks a million for the outstanding content.

Thanks a lot for your videos.
You are a saviour

Very good and very well explained, I study biomedical engeneering and this is teached to us in the first master and this was way better explained and visualised!i

Thank you my dude❤ very helpful

Hello! I hope you are doing great, I have learned a lot from your explanations. But I really need your help, I will have an exam and I have some multiple choice questions and I'm not sure of my answers. Can you help me please
I can send you the questions

This is the best video I had ever watched about mri physics and it would be amazing if you could have the transcript on the video

Thanks a lot, while I do love physicist lectures in the classroom, you can't exactly pause them and take notes, let alone rewind them as there is a schedule to keep up with. And in physics, devil is often in the details.

Amazing videos! Way more better than my lecturer!

Hi Michael, I have one question though, How can RF coil create perpendicular magnetic field? As the setup is such, the magnetic field generated by any coil can only be in longitudinal direction. BTW wonderful videos!!

very helpful

God bless you

Exceptional

I love you

wow. so far the best video about this topic. Thank you so much!

Thank u ! 🥺It helped alot ❤️❤️

If i had this when i was in school, life would have been so much easier. Kudos man, on my way to MRSO, just brushing up and i feel like ive grasped it even more. Thank you sir

Brilliant analogies! Even more brilliant explanations! You just taught me a concept I, apparently, wasn’t fully understanding after years of studying. How the magnetic moments are flipping exactly.

I always thought they flipped transversely and precessed like a top in that direction. That it flipped and spun in the same manner as it was pre-stimulation. Instead, they fan out, and at 90 degrees, the spin looks more like the face of a watch. Mind. Blown. 🤯

I take the registry in four days, and will probably blow it away. However, I wish I’d discovered you earlier to better understand the actual practical concepts. Either way, my coworkers will come to know your tutorials well. Thanks.

Medical imaging student here second year second semester. You're are an Angel. Grazie mille!!

Excellent videos! thanks for your labor!

F

you have single-handedly saved my semester in medical imaging

Please add subtitles

Right now I need you more than my girlfriend. Lol thank you great teacher.

Thanks so much for your great videos, they're extremely helpful! I've started reading several resources before coming here and things alweays didn't make sense to me whenever I reached the TR and TE principles but now I know understand what are these. Thanks again!

I had to constantly go back and rewatch the video because I keep getting lost in your eyes. So annoying.

Scared off by the first video?!!!!! Dude you made me fall in love, Thank you very much!

Thanks for your incredible lessons!!!
Best regards. Fourth semester of radiography . 😊

Thank you. appreciated efforts.. I liked the swing example

Quality content ❤

Thank you for creating this!!💓

Thx for Sharing your Knowledge

You are explaining this better than my professor who is co-building one of the stongest MRI-machines in the world himself, which does say a lot! Hats off and many thanks for this MRI physics series!❤

I see many people say MRI physics is hard and they barely passed , if most of them aren’t really understanding physics but still go on to become MRI techs , how important is MRI physics ?

Bravo

The best radiology channel

Can gradients make the magnetic field stronger than B0? Your illustration implies that the magnetic field to the right of iso-center is higher than B0 (for instance 1.5T) as a result of the gradient manipulating the field.

Your spin is precessing faster to the right of iso-center. Indicating a stronger magnetic field

omg this video costs a million dollars!
