Gel dosimeters are a three-dimensional imaging tool for dose distribution induced by radiations. They can be used for accuracy check of Monte Carlo simulation in particle therapy. An application was reviewed in this article. An inhomogeneous biological sample placing a gel dosimeter behind it was irradiated by carbon beam. The recorded dose distribution in the gel dosimeter reflected the inhomogeneity of the biological sample. Monte Carlo simulation was conducted by reconstructing the biological sample from its CT image. The accuracy of the particle transport by Monte Carlo simulation was checked by comparing the dose distribution in the gel dosimeter between simulation and experiment.
凝胶剂量计是一种用于辐射诱导剂量分布的三维成像工具。它们可用于粒子治疗中蒙特卡罗模拟的准确性检查。本文回顾了一项应用。将一个凝胶剂量计置于非均匀生物样品后方,用碳束对其进行照射。凝胶剂量计中记录的剂量分布反映了生物样品的不均匀性。通过从生物样品的CT图像重建该样品来进行蒙特卡罗模拟。通过比较模拟和实验中凝胶剂量计的剂量分布,检查蒙特卡罗模拟中粒子传输的准确性。
