Dose distribution for 10 mm anterior motion for a) bony based IGPT, i.e., the plan was moved from the pCT to the rCT based on bony anatomy, b) soft-tissue based IGPT, i.e. the fields are at the isocenter of the moved target after a soft-tissue registration and c) DGPT, where the preferred dose distribution have been chosen, which in this case is when the fields are moved 5 mm posterior towards the uncorrected position prior to IGPT.
