Fractionation principles
•
Conventional fractionation
: Dose per fraction
1.8-2.0 Gy, 5 fx/wk
•
Hyperfrationation
: Dose per fraction <1.8 Gy
•
Hypofractionation
: Dose per fraction >2.0 Gy
•
Split-course
: A treatment break (weeks),
resulting in prolonged overall treatment time
•
Accelerated fractionation
: Reduced overall
treatment time
