Abstract
Positional accuracy of the on-board imager (OBI) isocenter with gantry rotation was presented in this paper. Three different type of automatic evaluation methods of discrepancies between therapeutic and OBI isocenter using digital image processing techniques as well as a procedure stated in the customer acceptance procedure (CAP) were applied to check OBI isocenter migration trends. Two kinds of kV x-ray image set obtained at OBI source angle of
본 연구에서는 방사선치료용 선형가속기의 갠트리 회전에 따른 온-보드 영상장치(on-board imager, OBI)의 회전중심점의 위치 정확도 확인을 위해 제조사에서 제공된 고객인수시험절차서(customer accetpance procedure, CAP)상에서 명시된 방법을 비롯하여 OBI 선원 위치
