提供了对第一个商业上可获得的磁共振成像(MRI)引导放射治疗(RT)系统的描述。该系统由一个分体式0.35-T磁共振扫描仪组成，横跨3个Co-60头安装在环形门架上，每个头配备独立的双聚焦多叶准直器。MR和RI系统共享一个共同的等中心，从而在RI交付期间实现同步和连续的MRI。床上自适应RI治疗计划系统和集成的MRI引导RI控制系统允许基于软组织的可视化进行快速自适应计划和光束传输控制。华盛顿大学于2014年1月开始使用该系统治疗患者。(C)2014 Elsevier Inc.保留所有权利。
A description of the first commercially available magnetic resonance imaging (MRI)-guided radiation therapy (RT) system is provided. The system consists of a split 0.35-T MR scanner straddling 3 Co-60 heads mounted on a ring gantry, each head equipped with independent doubly focused multileaf collimators. The MR and RI systems share a common isocenter, enabling simultaneous and continuous MRI during RI delivery. An on-couch adaptive RI treatment-planning system and integrated MRI-guided RI control system allow for rapid adaptive planning and beam delivery control based on the visualization of soft tissues. Treatment of patients with this system commenced at Washington University in January 2014. (C) 2014 Elsevier Inc. All rights reserved.
