English(EN) From Data Completeness to Data Sufficiency: A Task-Driven Imaging Framework for Intraoperative CBCT under Quality-Time-Dose Trade-offs

新框架将术中 CBCT 从数据完整性重新定义为数据充分性

这篇综述论文提出了一个面向术中锥束 CT (CBCT) 的新框架,将焦点从“数据完整性”转移到“数据充分性”。作者认为,在当前的 CBCT 几何结构下,实现数学上的完整数据是不可能的,并且过度的采样会负面影响图像质量、成像时间和辐射剂量(Q-T-D 权衡)。相反,该论文提倡一种任务驱动的方法,优先满足临床决策所需的最低图像质量阈值,允许可接受的近似误差,以实现更好的 Q-T-D 平衡。 AI

影响 这项研究通过优化图像质量、扫描时间和辐射剂量之间的平衡,有望实现更高效、更安全的术中成像。

    Mobile C-arm cone-beam computed tomography (CBCT) has been widely used for real-time intraoperative 3D imaging. However, current practice often mechanically applies the fan-beam CT criterion of "180° plus fan angle" in pursuit of "data completeness" in reconstruction. This review…
