Examples

“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.”
