Bladder tumour-focused magnetic resonance image-guided adaptive radiotherapy using a 1.5 Tesla MR-linac is feasible. A full online workflow adapting to anatomy at each fraction is achievable in approximately 30 min. Intra-fraction bladder filling did not compromise target coverage with the class solution employed.
使用1.5特斯拉磁共振直线加速器进行膀胱肿瘤聚焦磁共振图像引导自适应放疗是可行的。在大约30分钟内可实现适应每次分次解剖结构的完整在线工作流程。采用的分级解决方案中，分次内膀胱充盈并未影响靶区覆盖。
