| Research Abstract |
Volumetric modulated arc therapy(VMAT) is a rotational intensity-modulated radiotherapy(IMRT) technique capable of acquiring "in treatment" projection images for cone-beam computed tomography(CBCT). CBCT during treatment is expected to evaluate the actual tumor position and dose distribution. The goal of our research is to establish a new method of verification during treatment in stereotactic body radiotherapy(SBRT). In this study, we carried out SBRT using VMAT in consideration of respiratory motion and have successfully shown that the movement of the tumor "in treatment" using 4D-CBCT.
