Real-time tumor-tracking radiotherapy system with monoscocpic imaging system

在这项研究中，提出了一种可用于门控放射治疗的新型单目成像系统。该系统可减少治疗过程中因脉冲透视而产生的成像剂量，并可实现系统紧凑。通过使用实际标记位置和实际标记轨迹进行评估，结果表明，该方法的测量误差在大多数情况下都在可接受的水平内。此外，还可以通过优化成像几何结构来最小化测量误差。结果表明，该方法具有临床应用的可行性。

In this study, the novel monoscopic imaging system that can be utilized for gated-radiotherapy is proposed. The proposed system can reduce imaging dose due to pulsed fluoroscopy during treatment and can realize compact system. It was shown that the measurement error of the proposed technique was within acceptable level in most cases by performing the evaluations with actual marker positions and actual marker trajectories. In addition, the measurement error can be minimized by optimizing imaging geometry. As a result, the feasibility for clinical use was shown.
