Portable vs in Dept.

What's the difference between the radiation emitted by a portable machine and the radiation emitted by a regular xray machine? Absolutely nothing. By utilizing, say, 110 kilovolts and a 12:1 grid with perpendicular centering you should get the same image regardless. It is operator error that will produce a difference. Sometimes I wish other hospital staff knew that, but alas, for another 2 years I'll be stuck at this level on the totem pole and have to just do what I'm told, one of the more frustrating aspects of this profession.
