Abstract
Purpose: The aim of this study is to evaluate the dosimetric properties of robust planning strategy for plain intensity-modulated proton therapy (IMPT) taking into account of the uncertainties of effective proton range and set up error as compared to photon intensity-modulated radiation therapy (photon-IMRT) in prostate cancer treatment. Materials and Methods: The photon-IMRT (7 beams, step & shoot), plain-IMPT (2, 4, and 7 portals), and robust- IMPT plans, which was recalculated the plain-IMPT based on the uncertainties of range error (
목 적: 양성자선의 유효비정 변화와 환자 자세의 재현성을 고려한 로버스트(robust-IMPT) 세기조절양성치료와 플레인 세기조절양성자치료(plain-IMPT) 계획과 광자선 세기조절방사선치료(photon-IMRT, step & shoot) 계획의 선량분포 특성을 비교, 분석하고자 한다. 대상 및 방법: 다섯 명의 전립선암 환자를 대상으로 표적에 70 Gy를 조사하도록 photon-IMRT (7문, step & shoot)와 plain-IMPT (2문, 4문, 7문) 및 robust-IMPT (유효 비정 오차
