Example for adapted 66 Gy and 82 Gy boost plans.

The replanning steps and the cumulative dose distribution are shown for a 66 Gy plan (no boost) on the left and for 82 Gy with SIVAB (16 Gy boost) on the right. A 66 Gy plan was created on each CT scan with the cumulative plan consisting of a) 15 fractions based on the initial CT, b) 10 fractions of week 2 CT, and c) 8 fractions of the week 4 CT simultaneous integrated volume-adapted boost plan, adding up to a total dose between 66 Gy (no boost) and 82 Gy (16 Gy boost).

Colorwash red: planning target volume (PTV) based on the respective initial, week 2 and week 4 CT scan, colorwash blue: PTV boost, colorwash purple: planning organ at risk volume (PRV) esophagus, colorwash green: PRV spinal cord.
