| Research Abstract |
In this research, I developed a four dimensional(4D) cone-beam CT(CBCT) during course of treatment and during treatment by using linac-mounted diagnostic kV X-ray, which corresponds to time-dependent variation of the irradiated cites. With the 4D CBCT, I established the system to verify a cumulative dose distribution in a patient by introducing non-rigid registration(deformable image registration). Through this study, the method to estimate an irradiation accompanied by CBCT imaging and the image processing automation were developed.
