Dose calculation system using in-treatment cone-beam CT for adaptive radiation therapy

在这项研究中，我开发了一个四维（4D）锥束CT（CBCT）在治疗过程中，并在治疗过程中使用直线加速器安装诊断kV X射线，这对应于随时间变化的照射部位。通过4D CBCT，我建立了系统，通过引入非刚性配准（可变形图像配准）来验证患者体内的累积剂量分布。通过这项研究，方法来估计伴随CBCT成像和图像处理自动化的照射。

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.
