So I am understanding that when we have a smaller anode angle that there is more photon interaction occurring at the anode heel, but is that a good thing or bad thing? and how is it affecting the receptor exposure for a small angle or larger angle?

Hi again. SO...would you recommend a small focal spot (and the increased/tighter collimation) for small body parts (extremities)? If not, why not?

I am still confused how oid does not effect receptor exposure? In terms of air gap there would be less scatter to patient that would reduces exposure correct? Or is it still the same amount of exposure just the scatter photons will miss the board?

Hello I have a general question how does contrast ties in with OID. It states when Oid increases contrast increases
