The number of pencil beam scanned proton therapy (PBS‐PT) facilities equipped with cone‐beam computed tomography (CBCT) imaging treating thoracic indications is constantly rising. To enable daily internal motion monitoring during PBS‐PT treatments of thoracic tumors, we assess the performance of Motion‐Aware RecOnstructiOn method using Spatial and Temporal Regularization (MA‐ROOSTER) four‐dimensional CBCT (4DCBCT) reconstruction for sparse‐view CBCT data and a realistic data set of patients treated with proton therapy.

技术说明：从稀疏视图CBCT数据重建4D锥束CT，用于铅笔束扫描质子治疗（PBS-PT）中的日常运动评估

配备有锥束计算机断层扫描（CBCT）影像学治疗胸部指征的铅笔束扫描质子治疗（PBS-PT）设施的数量正在不断增加。为了使日常内部运动期间胸部肿瘤的PBS-PT治疗监测，我们评估的性能中号otion-甲洁具- [R EC ö nstructi ø N法使用小号（ε2）和碲mporal ř egularization（MA-雄鸡）四维CBCT（ 4DCBCT）重建，以获取质子治疗患者的稀疏CBCT数据和真实数据集。
