| Outline of Final Research Achievements |
For patients with small lung tumor treated with intensity modulated radiation therapy, we established methodology for estimating actual delivered dose distributions taking account for respiratory motion. Based on logs including gantry angle, monitor unit, and the position of multi-leaf collimators during beam delivery, actual dose distribution on each respiratory phase was calculated. Then, accumulated dose distribution was simulated using deformable image registration. The present method successfully reconstructed accumulated dose distribution. The difference between this simulated dose and planning dose was reported in academic conference and will be reported as academic article.
