OOPS I found an error at Error at 9:31 ! Photoelectric Energy Range is not 10keV to 150keV the minimum can be as low as 0.3keV. Guess the proper energy range is from the k-shell binding energy of a low atomic number atom up to 150keV. The minimum energy for a photoelectric effect is the binding energy of the k-shell electron and for low atomic number atoms, such as those found in soft tissue, the binding energy of even K-shell electrons is low (e.g., 0.3 keV for carbon).
Thank you SO much for your videos. I can't emphasize how much your videos have help me. Your videos really helped me understand so much. You're so great at explaining everything! Thank you thank you thank you!
English is my second language and for me takes a little bit longer to understand my professors. But with your videos are being helping me a lot! . Thanks!!
It was an excellent presentation. I have a doubt on the occurrence of multiple scattering takes place at the Compton scattering. How does the multiple scattering on Compton finally leads to photoelectric effect ? Coz as the multiple scattering takes place the wavelength of the X-rays will be keep on reducing r8, then how comes the photoelectric absorption can occur with the energy less then that of required for compton scattering.? Kindly clarify me ! Thanks in advance.
These interactions are occurring in the body which means the atom that will photoelectrically absorb the x-ray photon might be atoms of Calcium or Oxygen or Carbon. These atoms have rather low K Shell binding energy levels. So a 60 kEv x-ray photon might exit the tube and enter the patient and have several Compton Scattering interactions, each reducing the energy of the x-ray photon and then eventually get photoelectrically absorbed by a Calcium atom. Hope that clarifies.
The Photoelectric effect occurs at photon energies way below that required for Compton scattering. So your list at 0:29 should swap Photoelectric and Compton to be in the correct order of energies. Excellent presentation overall!
this was incredibly helpful, my classmate and i are so much more understanding of this chapter since watching your video. thank you so much
Best clip on image formation on TH-cam. Thanks!

It sounds like you're really smart, which is very cool.

thanks :) i hope you can create a discussion of every lesson of bushong book.thanks
Thank you, this video help me through the exam!
Thank you for taking time to teach us
The best explanation!!! Thank you very much!!!
My thanks for the lecture. i'm gonna make a resume of the lecture for homework. so that's an auto sub for you sir. GG TY
I don't know who to thank you 💜
Thank you for posting this video lecture.
Coherent scattering is also referred to as elastic scattering. Well done
Amazing. Please make more.

Greg thanks for pointing out that error.
Great presentayion
Character In the video It's great, I like it a lot $$
Thank you so much sir video is very useful
Scatter Outta Compton?
What happens after with an electric photon ?? Is it possible to produce bremsstrahlung inside the human body through this interaction ??
Your Awesome, thanx a lot
i understand your lesson than my teachers in school. hahahaha
Radiation Hazards and protection short notes
Hi Xray Bob is there anyway I can get ur powerpoints for personal study? Thanks
thank you, this is awesome. you should consider teaching.
Thank you. I do teach.
Ok, now I envy your students :)
Thanks thanks thanks
Thank you !!!!!!!
Very bad presentation
I agree
