Abstract

We are evaluated the usefulness of radiation treatment planning applied respiration factor for stereotactic body radiation therapy in the lung cancer. Four dimensional computed tomography images were obtained in 10 patients with lung cancer. The radiation treatment plans were established total lung volume according to respiration images (new method) and conventional method. We was analyzed in the lung volume, radiation absorbed dose of lung and main organs (ribs, tracheobronchus, esophagus, spinal cord) around the tumor, respectively. We were confirmed that lung volume and radiation absorbed dose of lung and main organs around the tumor deference according to applied respiration. In conclusion, radiation treatment planning applied respiration factor seems to be useful for stereotactic body radiation therapy in the lung cancer.

본 연구는 폐암 환자의 정위방사선치료 시 환자의 호흡인자를 적용한 치료계획을 설정하여 그 유용성을 평가하고자 하였다. 폐암 환자 10명을 대상으로 4차원 컴퓨터단층촬영을 시행하고, 환자의 호흡 인자를 적용한 치료계획과 기존의 치료계획과 비교 평가하였다. 실험은 폐의 용적변화, 폐의 방사선 흡수선량 변화, 폐암 주위의 중요 장기의 흡수선량 등을 분석하였다. 본 연구에서 호흡인자를 적용한 방사선 치료계획 시 기존의 방법과 비교하여 폐의 용적변화, 폐의 방사선 흡수선량 변화, 폐암 주위의 중요 장기의 흡수선량의 차이를 확인할 수 있었다. 결론적으로 폐암 환자의 정위체부방사선치료를 위하여 호흡인자를 적용한 방사선 치료계획 방법은 유용할 것으로 사료된다.
