Outline of Final Research Achievements

In this study, positional accuracy and corresponding set-up margin were evaluated in order to establish a uniform set-up margin calculation for prostate cancer, non-small cell lung cancer, and esophageal cancer. And also, the positional accuracies for head, chest and pelvic regions were evaluated and basic data for the margin calculation method were acquired using cone-beam CT and kV-X-ray systems. The results in this study could be contributed to the establishment of a foundation for the radiotherapy based on evidence-based medicine while reducing an uncertainty with respect to set-up margin.
