Amazing amazing, 12 min took me to understand this when I tried 2 hours with no luck

Nice explanation❤

Thank you so much 🤍

Simplest explanation ever. Thanks , helps a lot.

I’m so glad it helped Nishant. Simpler the better in my opinion when it comes to physics!

Thank you it was very helpful, I'm a 2nd year college, taking a radiologic technologist,❤

Thank you very much for your great videos. I have a question though. what do you mean by saying ' Now these gray blocks here represent lead sheets that will attenuate our x-ray beam lay. It has a high atomic number. And we saw with the photoelectric effect, the higher the atomic number, the more likely the photoelectric effect is to occur', I really can't get my head wrapped around this phrase, I heard it in the previous video too but I don't get it. I'd really appreciate a brief explanation

Your videos are phenomenal! Thank you for all these resources/explanations. Just had a question about what you said at 00:04:26 How does collimating improve spatial resolution? Shouldn't it only affect contrast by decreasing scatter (scatter kills contrast)? Especially since our FOV hasn't technically changed (Matrix number, pixel size, etc). Similar to grid spatial resolution - "Because the grid does not change the size of the focal spot or the size of the pixels in the image matrix, it does not influence spatial resolution."

Thank you Dylan! You’re correct ✅ my mistake, meant to say collimation improves contrast resolution! Thanks for letting me know 👌🏼

These lectures are 👍 great. Not sure how I just discovered you now.

Hi! Thank you for the very informative video (they are great!!). I have a question; does the cathode/anode difference in photon projection still apply when collimating since the lead sheets attenuate most of the lateral X-rays being projected? I watched your cathode vs anode photon projection video and was just curious. Sorry if this is common knowledge, I am going to school in July for X-ray school and I am just trying to get a good idea of how things work. Thanks a ton! Your videos are so helpful!

Hi Megan. Great question! The cathode anode difference (tube potential) determines both the average energy and number of x-ray photons produced. Collimation attenuates x-rays from the outer portion of the beam but does nothing to the x-rays still reaching the patient. Therefore, if cathode anode difference changes the energy and the number of photons reaching the patient (despite collimation) will still change. Watching the ‘factors that influence the x/ray spectrum’ video should help. Feel free to reach out if you have any more questions 🙂
