| Research Abstract |
As a safety method for measuring organ motion in respiratory-gated radiotherapy, we studied and developed a quantitative tracking method for organ motion. Our proposed method uses a large number of feature points to achieve a suitable tracking for a long term. The method was validated for moving phantom images and the subject images, and the result showed that our proposed method was possible to track some parts of organ for a long term.
