    After being out of the field for several years and having taken my exam in 2007, I have to retake my exam. Your videos have been a life saver. Just want to thank you so much for all your work and tips.

    Hi Meaghan, you say that filtration decreases receptor exposure. But given that filtered x-rays have very low energy, wouldn’t they just be absorbed in the patient if there were no filtration? If so, how does filtration actually make a difference to receptor exposure?

      There would never be no filtration. The entire job of filtration is to remove the low energy photons in the beam that would increase the patient skin dose. Filtration reduces the total quantity of the beam, so in turn reduces receptor exposure. The scenario is often... if filtration is increased how would it affect... quality? quantity? skin dose? receptor exposure? for example.

    How is there a direct relationship with anode heel effect, but when anode heel effect increases the receptor exposure goes down? At least thats what my kettering book photographic factors says.

      Hi, I used anode degree on this example. Decreased anode angle would increase anode heel effect. Heel effect and anode angle are different terms.
