论文摘要
如果在患者治疗期间出现未注意到的错误，近距离放射治疗的源特征附近的高剂量梯度等同于邪恶作用。体内剂量测定是量化输送剂量的唯一方法。先前对此的研究表征了可以用作体内剂量计的潜在探测器。他们中的一些人专注于HDR近距离放射治疗中的来源跟踪主题。这项研究的目的是通过结合来自两个独立检测器系统的体内剂量测量测量来执行3D源位置重建。第一个基于多个（三）塑料闪烁体检测器，第二个基于单个无机晶体（CSI：TL）。通过组合两个检测器响应，我们启用了3D空间中绝对源坐标的确定。这项研究中提出的方法可以扩展到不同系统的组合。
The high dose gradients near the source characteristics of brachytherapy are equivalent to nefarious effects if unnoticed errors take place during the patient treatment. In vivo dosimetry is the only method to quantify the delivered dose. Previous studies to this one, have characterized potential detectors that can be used as in vivo dosimeter. Some of them have focused on the source tracking topic in HDR brachytherapy. The aim of this study is to perform 3D source position reconstruction by combining in vivo dosimetry measurements from two independent detector systems. The first was based on multiple (three) plastic scintillator detectors and the second on a single inorganic crystal (CsI:Tl). By combining two detector responses, we enabled the determination of the absolute source coordinates in 3D space. The method in this study proposed can be extended to the combination of different systems.
