초록
목 적: 유방 보존 수술 후 방사선 치료를 받는 Large pendulous breast 환자에 있어서 엎드린 자세의 유용성을 평가해 보고자 한다. 대상 및 방법: 동일 환자에게 Breast board를 사용한 바로 누운 자세(Supine position: SP), Breast Supporting Device를 사용한 바로 누운 자세(Supine position with breast supporting device: SD), 그리고 Custom Prone mattress를 사용한 엎드린 자세 (Prone position: PP)를 모두 적용하였다. 각 방법에 대해 전산화단층촬영(High Advantage, GE Medical System, USA)을 시행하였고, 3차원 치료계획용 컴퓨터(
Purpose: To evaluate dosimetry results of three different techniques for whole breast irradiation after conservative surgery of large pendulous breast patient. Materials and Methods: Planning computed tomography (CT) scans for three techniques were performed on a GE Hi-speed advantage CT scanner in the supine (SP), supine with breast supporting Device (SD) and prone position on a custom prone mattress (PP). Computed tomography images were acquired at 5 mm thickness. The clinical target volumes (CTV), ipsilateral lung and heart were delineated to evaluate the dose statistic, and all techniques were planned with the tangential photon beams (Pinnacle
