국문 초록
4DCT와 저분할 고선량 세기방사선치료기법으로 인해 방사선치료범위는 작아지고 있다. 따라서 방사선치료 시 방사선 조사 위치 정확도는 매우 중요하다. 방사선 치료 시 정확도 향상을 위해 온보드 영상장치(on board imager)와 콘빔CT(conebeam CT)를 이용하여 환자의 자세와 종양 위치를 확인하고 있으며, 최근 선형적(linear) 위치이동을 통한 환자 자세교정 뿐만 아니라, 6D couch의 yaw, pitch, roll을 이용한 축 회전 위치이동을 통해 자세교정을 한다. 본 연구는 마이크로컨트롤러와 6축 자이로/가속도센서를 이용하여 6D couch 축 회전 각도 QA 장치를 개발하였다. Yaw, pitch, roll 각도를 0도를 기준으로 ±3° 각도를 1° 범위로 측정하였다. 개발한 6D couch QA 장치는 실시간 축 각도 측정이 가능하였으며, 측정된 데이터를 통해 사후 분석이 가능하였다.
