Outline of Final Research Achievements

The purpose of this study was to develop a new 4D dose calculation system for intensity modulated dynamic tumor-tracking radiotherapy (IM-DTRT).
Dose calculation was performed using ten phase CT with the x-ray head rotated by the corresponding angle for pancreas IM-DTRT.
The mean dose differences between the IM-DTRT and the conventional plans for stomach and duodenum were approximately 40% and 20%. The dynamic tumor-tracking plan can reduce organs at risk dose with high dose prescription for the target.
