Eric, Thank you very much for the reply. I remember being asked a question on the exam last year about why Auger vs X-Rays but I had no idea. Your explanation more than suffices as the examiners are not quantum physicists either. I have never seen that graph before showing the propensity...

Auger electrons Dear Eric, Thank goodness I am now off clinical duty and in my office studying as I enter the home-stretch toward my exam! My next question is about Auger electrons: Bushberg states: "An electron cascade does not always result in the production of a characteristic...

Eric, I read your reply yesterday, but I am up to my neck in cases this week. Thank you very much for wonderful explanations of my first 3 questions. I am studying with 2 other radiology residents, and it's the blind leading the blind with nitty gritty physics concepts. Your help is sooooo...

Ok. Specifically, the following paragraph from Bushberg reads: “The existence of the space charge cloud shields the electric field for tube voltages of 40 kVp and lower, and only a portion of the free electrons are instantaneously accelerated to the anode. When this happens, the operation...

Dear Berkeman and EricVT, Thank you very much for offering help with physics! I am in over my head with chaos since I am trying to study for this exam and work full time. Your help is soooo appreciated. :) OK. Yes, I do know a good bit about the topics I mentioned in my first thread...

I am taking my radiology board exam on Sept 7, and I need some urgent help with certain concepts if the help can be found. Concepts I am struggling with include but definitely are not limited to: 1. transformers (step-up / step-down) 2. spatial resolution 3. image formation in digital...
