PBT is unique as there are relatively fewer side effects then oxidizing radiation. I would imagine that the IMRT part of it would be substantially less, then if it was the only treatment modality.

PBT is unique in that it applys a charged particle that only reaches it's full potential when actually at the precise target - resulting in minimal collateral damage.

It must be good as MDACCC invested $200 million in a dedicated facility for it. There are only about 1/2 dozen PBT treatment centers in the US today.
