Relationship of Target Volumes for moving target — Medical Physics

Dr. Jin Sung Kim introduced an insightful video clip to give you a better understanding of target volumes for moving target in radiation therapy. This clip visualize a concept of moving target volume which was reported by Wolthaus et al., 2006.

방사선치료에서 Target Volume이라는 것은 중요한 의미를 가진다. 어디까지 수술을 해야하느냐.. 와 동일한 의미로.어디까지 방사선을 주어야하느냐.. 를 결정하기 때문이다.그러한 Target Volume에는 GTV, CTV, ITV, PTV 등이 있고, 이에 대한 자세한 설명은 ICRU 50, 62, 83 레포트를 보면 확인할 수가 있다. 그 중에 움직이는 종양에 대한 정의를 하기 위해서 2006년 Wolthaus가 보고한 논문의 그림이 있는데, 강의자료로 사용하기 위해서 유사하게 그려보았고, Powerpoint의 기능을…
