Ive been going back and forth in my physics in medical imaging textbook still not fully grasping the key concepts, Sir your videos are literal godsent. Suddenly my textbooks starts to make sense. Thank you!
So this is it. 1st year med student in France, was extremely stressed about this chapter that we are suppose to master before the end of semester. We had a senior radiologist come as a teacher and let's say that in 4 hours she killed me (still have the dosimetry chapter to catch up but this one was by far the most scary one for me). I felt totally helpless in the face of the amount of information and details that I needed to know (but above all understand) which really made me panic and I had the feeling of not being up to the task. I've heard people say that they were just going to memorize by heart the course because they didn't understand anything, but thanks to your remarkable work, I'm no longer in that situation ! So this long message to say THANK YOU. Your videos are visual, you keep the essence of the knowledge and you make the effort to explain the links between each thing, which gives meaning to what we learn. I took lots of notes thanks to this series and I'm going to use them, that's for sure :) This part was a significant part of my semester and I went from fear, incomprehension to peace and clarity (it seems like I'm talking about a weird conversion haha) but it It was a weight on my head and I don't have it anymore. More than the "factual" side, I will say that you made this course interesting and that is worth all the applause. I hope you still find joy in teaching the way you do because it's been a real pleasure, and who knows, maybe I'll come back and find your videos later ?
Very excellent video. How can I calculate HVL for polychromatic x-ray beams, not a monochromatic beam? How can I calculate the effective energy for a specific x-ray spectrum? thanks in advance
So, let's say I bombard a 0,9cm thick layer of lead with 1meV, it's halved after those 0,9cm. Then to reach 25% of the initial photon energy, I'll need another 0,9cm of lead?

I’m so glad. Feel like it was what I needed when I was struggling with my textbooks the first time round! Glad they’re helpful 🙂
Very nicely presented, excellent presentation. I wish 10 M subscribers for this channel
Thank you so much 😀

Really awesome sir. Very easily explained
Thank you 🙏🏻
Undoubtedly Best video lectures available for Radiology Students.
I'm so glad you think so 🥳
Thanks for the example!
Glad it was helpful!
Brilliant explanation
Thank you Ruth!
Sir when will be the CT and MRI physics lectures available?
I’ve just started creating the MRI slides. Hoping to start next week 👌🏼
@@radiologytutorials sir and CT too ..we would be highly obliged ❤️
Of course. CT after MRI
@@radiologytutorials sad :( ive got mri exam next week hahaha thank you for your videos it has been really helpful
😭😭 bleak! Wish I could have come through for you Hanafie! I’m sure you’ll do great! Good luck for the exam 🙂
I am a nuclear engineering student and having a course on health physics...So i am here before semester final...
USG physics
And MRI PHYSICS
So, let's say I bombard a 0,9cm thick layer of lead with 1meV, it's halved after those 0,9cm. Then to reach 25% of the initial photon energy, I'll need another 0,9cm of lead?
Exactly! (Assuming the beam is monoenergetic) 🙂
Thanks...
Please confirm an analysis:
Total No.of incident X-rays / photon reduction factor = No.of exiting X-rays
