目的：进行一项计划研究来评估 RapidArc (RA)（一种容积调制弧技术）治疗恶性胸膜间皮瘤的效果。基准为常规固定场调强放射治疗（IMRT）。方法和材料：纳入6例患者的计算机断层扫描数据集。将具有九个固定光束的 IMRT 计划与具有单个等角点的双调制弧进行比较。所有计划均针对 15-MV 光子束进行了优化。剂量处方为计划目标体积 54 Gy。规划目标体积的规划目标是最小剂量 >95% 和最大剂量
Purpose: A planning study was performed to evaluate RapidArc (RA), a volumetric modulated arc technique, on malignant pleural mesothelioma. The benchmark was conventional fixed-field intensity-modulated radiotherapy (IMRT).Methods and materials: The computed tomography data sets of 6 patients were included. The plans for IMRT with nine fixed beams were compared against double-modulated arcs with a single isocenter. All plans were optimized for 15-MV photon beams. The dose prescription was 54 Gy to the planning target volume. The planning objectives for the planning target volume were a minimal dose of >95% and maximal dose of
