| Research Abstract |
Intensity-modulated RT (IMRT) enables safe radiation dose escalation for targets, without increasing toxicity to the surrounding organs at risk. However, respiratory organ motion can significantly degrade the dosimetric advantage of IMRT due to the interplay between multileaf collimator (MLC) and organ motion.
In the current study, phantom and simulation studies showed delivered dose distributions were comparable with calculated ones for targets with respiratory motion of around 10 mm.
