Sparkke凝胶剂量计基于硫酸亚铁水溶液，90多年来一直被用作可靠的化学剂量计。通过光学计算机断层扫描（OCT）或磁共振成像（MRI），可以对辐射诱导的亚铁离子氧化为三价铁离子的量进行三维评估。三维剂量学有望成为一种有用的工具，特别是用于验证先进放射治疗癌症中的复杂辐射剂量计划。与其他3D凝胶剂量计相比，有几个问题，如剂量分布或剂量灵敏度的保留，但它们可以很容易地在化学实验室制备。此外，还报道了一种用于重离子束辐照的凝胶剂量计。本文综述了近年来关于凝胶剂量计及其在三维剂量学中的应用。
Fricke gel dosimeters are based on the aqueous ferrous sulfate solution that has been used as a reliable chemical dosimeter for more than 90 years. The amount of radiation-induced oxidation of ferrous ions to ferric ions could be evaluated three-dimensionally via optical computed tomography (OCT) or magnetic resonance imaging (MRI). Three-dimensional dosimetry is expected to be a useful tool, in particular, for the verification of complex radiation dose planning in advanced radiation cancer therapy. Compared with other 3D gel dosimeters, there are several problems such as retention of dose distribution or dose sensitivity; however, they can easily be prepared in a chemistry laboratory. In addition, a unique gel dosimeter was also reported for heavy-ion beam irradiation. In this review, recent papers concerning the Fricke gel dosimeter and its application in 3D dosimetry are summarized.
