Outline of Final Research Achievements

Volumetric modulated arc therapy (VMAT) is capable of acquiring respiratory signals derived from projection images and machine parameters based on logs during VMAT delivery. The purpose of this study was to reconstruct the dose distribution during stereotactic body radiotherapy (SBRT) using VMAT. The present method successfully reconstructed the dose distribution using the respiratory signals and machine parameters acquired during treatment. This is a feasible method for verifying the actual dose distribution for a moving target.
