dc.description.abstract환자의 호흡은 방사선치료에서 중요한 인자로 작용한다. 종양을 치료하는 방사선 치료용 선형가속기에서 시행하는 기존의 cone-beam CT에서는 호흡에 의한 움직임이 반영되지 않아 영상에 왜곡이 발생하여 정확하지 못한 영상 정보를 획득하였다. 본 연구는 호흡에 의한 움직임을 고려하고 특정 순간을 포착한 gating을 적용하여 획득한 back projection 영상을 이용하여 cone-beam CT 영상으로 재구성하였으며 기존의 방법과 비교하였다. 기존의 방법은 영상 왜곡도가 400%에 달하였으나, 본 연구에서 시행한 gating을 적용한 cone-beam CT는 약 2%에 불과하였다. 이에 본 연구는 호흡의 움직임을 반영한 영상유도 방사선치료의 방향과 평가 방법을 제시하였다.The respiration is one of important factor in the radiation therapy. The existing commercial method of cone-beam computed tomography on LINAC does not consider respiratory motion of patient hence the images are both distorted and inaccurate. In this study, the cone-beam computed tomography images have been reconstructed from back projection radiography of specific phase on breathing cycle which concerned about respiratory movement in radiation therapy. This study investigated how different between cone-beam CT images with and without gating respiratory movement, and this paper provides that guide and implementation of gated cone-beam CT on radiation therapeutic equipment.en_US
