| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | During treatment fraction, accurate tracking of moving tumor by using X-ray imaging is important for radiation therapy. However, superimposition of tumor and other structure in X-ray image can reduce tracking accuracy. In this study, a moving target extraction method taken into account the transparent characteristic of X-ray by using Gaussian mixture model (GMM) was evaluated by using an X-ray image sequence of a 3D printed dynamic phantom based on clinical CT volume data. In comparison with other method, the moving target extracted by the GMM-based method was similar to the original phantom and improved tracking accuracy. |
