- Treatment with several doses per day offers the prospect of a significant therapeutic gain using readily available low LET beams. These regimens can be classified as either accelerated fractionation or hyperfractionation according to their rationales. With accelerated fractionation a conventional number of dose fractions is delivered in a significantly shortened overall treatment time in order to reduce the opportunity for tumor cell regeneration during treatment. With hyperfractionation, on the other hand, a large number of significantly reduced dose fractions is used to give a greater total dose in a conventional overall treatment time.
