As I understand the technology IMRT is delivering the same amount of energy to the target. The issue is whether the target is everything or something less than everything. I read here (by non profesionals) what amounts to guesswork. None of us know what the specific maping layout is for any patient here. For us to question specific treatments is out of line. We are not trained on the myriad details of radiation therapy. IMO, There is no reason to believe that properly planned IMRT is less effective than XRT. I would love to have a RO speak here to resolve any questions we have.

Also I do not believe XRT is the same as 3D conformal.
