this is hands down one of the best way to start your MRI journey by watching this video - thank you
Hey, biomedical engineer here, writing my thesis on MRI sequences. Your videos are an AMAZING visual break from all the convoluted terminology and as an ADHD who has a hard time going back and forth through heavy text to connect the dots, I really appreciate your effort!
Keep up the great work!
Thank you. I’m studying for MRI and this is so helpful
Another biomedical engineer here, a great video. I was very confused in this topic and after watching your video it just makes sense now. Great content!
Thanks, this is one of the clear videos about this concept
It's so lovely seeing your face after getting used to your voice in these videos for so long! Thank you for this video and for this series.
For the first time I understand MRI. Thank you!
Medical Physics student here and I have a final exam tmr, this was amazing ! Thank you!
I really appreciate providing much information in short time
Thank you! Very easy to digest !
Excited 😁
Thank you!!
great content .Appreciate it brother
Great explanation, thank you very much!!!!
Amazing Series. Thanks.
Great explanation
Great stuff.
one of the best. thanks.
Really valuable. Thank you so much.
Thankyou! Amazing
Super nice explaination! I like this MRI course, but it seems that only the first 3 courses are uploaded, could you update the later 3 course?? Really looking forward to seeing it!
Bravooo finally hv understood this part👏👏thank you sir, it's simple and very clear
Thank you make such a useful video 🤗
Thanks a lot 💓
Awesome
Hello! Great video! I'm just a little confused about the position of the coil that receives the RF pulse. Is it supposed to be parallel or perpendicular to the xy plane? Because I've found somewhere on the internet that it's supposed to be perpendicular but here it looks parallel. Can someone please explain? Also I know the coil must be perpendicular to the B0 vector (then it is perpendicular to the z axis) - that's my teacher told me at least haha.
Thanks for the video
im lucky, cause i just started my radiology course today and this video is uploaded just four days ago.
thanks for the video
Hey Dr. Bhayana, I am an MS4 thinking of applying to Radiology in part because I have a background in Physics (BS, graduate coursework in QM). How much can an advanced understanding of radiologic techniques and the physics behind them improve one's clinical ability as a radiologist? How far could my background in physics take me in my potential career as a radiologist?
Thank you please I want to do some exercices to understund (please do you have a book where I can find exercice ) Thank you
YESSS!!!!
good

Some inaccuracies in explanations - in the enthusiasm to 'make it simple' and fast: For example, precession happens right after the application of the external magnetic field B0. That they precess IN PHASE - upon the application of an RF pulse of frequency that of the Larmor frequency - due to resonance - is the subtle but crucial part missing here... It is the "IN PHASE" that is critical.
...contd. The point is, that precession happens right after the application of the external magnetic field, and the RF signal only makes it precess IN PHASE/SYNC. It is the precession in phase, that produce a rotating transverse field, that is detectable by a coil in the vicinity...
Am so much confused as the physics is very difficult to understand..am trying since morning and thanks now to het my point in a simpler way...
you do not require B1 in order for the nuclei to precess around B0 axis... this is wrong
Can you elaborate? I sought this video out because the ASRT course isn't explaining it in a way I get it. During the RF pulse, is the precession of the nuclei fixed on one vector 90° from B0, or is it precessing in a 360° arc on a plane 90° from B0 like I think he illustrated here?
@@squirreltakular9049 precess at 90 degree in xy plain
Is there a follow up vid or continuation of the series ?
