摘要
新的更为复杂的放射治疗技术要求辐射剂量计能够准确的测量三维剂量分布,提供高的空间分辨率。聚合体凝胶剂量计是最近才发展的新型剂量计,能够很好的解决三维剂量分布测量的问题。现综述聚合体凝胶剂量计的原理、制备、特性、成像、刻度方法和医学应用。
New, complex radiotherapy delivery system techniques require dosimeters that are able to measure three-dimensional dose distributions accurately and with good spatial resolution. Polymer gel is an emerging new dosimeter being applied to thesechallenges. The review gives the concepts of polymer gel dosimetry used for medicine, including principles, manufacture, characteristics, imaging, calibration method, and medical application.
