The research I'm doing for my PhD is taking a bit of a detour from the original plan to look at scatter radiation. Now I'm going to be studying patient dose from an "energy imparted" point of view and the work on scatter radiation is moving to a secondary role.
"Energy imparted" is a relatively new term to me, but now that I've done some literature searching and reading up on it, it turns out to be a very familiar quantity.
The absorbed dose to a volume of matter is defined as
where E is the amount of energy deposited and m is the mass of the volume.
Turns out E = energy deposited == energy imparted. Duh. *lightbulb*
More later as I continue reading.
