In respect of radiation dosimetry, several applications require dose distribution verification rather than absolute dosimetry. Most protocols use radiological and radiochromic films and ionization chambers or diode arrays for dose mapping. The films are disposable which causes the precision of the results dependent on film production variability. The measurements with arrays of ionization chambers or diodes mainly lack spatial resolution. This review aims to provide an overview of the use of optically stimulated luminescence detectors (OSLDs) for one-dimensional (1D) and two-dimensional (2D) dose mapping in different applications. It reviews the ideas, OSL materials, and applications related to the assessment of dose distribution using OSLDs in the form of film or ceramic plate (BeO). Additionally, it reviews research published in the international scientific literature from 1998 to 2021. As an outcome, a table containing the main characteristics of each relevant paper is shown. The results section was divided by the type of OSL material, and we briefly described the principal findings and the significant developments of each mentioned study such as film production and OSL reader assembly. The purpose of this study was to present an overview of the main findings of several research groups on the use of OSLD in the form of film or plate for 1D and 2D dose mapping. Finally, the potential future development of dose mapping using OSLD films was outlined.
在辐射剂量测定方面,一些应用需要进行剂量分布验证而非绝对剂量测定。大多数方案使用放射学和放射变色胶片以及电离室或二极管阵列进行剂量映射。这些胶片是一次性的,这导致结果的精度取决于胶片生产的可变性。使用电离室或二极管阵列进行测量主要缺乏空间分辨率。本综述旨在概述光激发发光探测器(OSLD)在不同应用中用于一维(1D)和二维(2D)剂量映射的情况。它回顾了与使用以胶片或陶瓷板(BeO)形式的OSLD评估剂量分布相关的理念、OSL材料和应用。此外,它还回顾了1998年至2021年国际科学文献中发表的研究。结果展示了一个包含每篇相关论文主要特征的表格。结果部分按OSL材料类型划分,我们简要描述了每项提及研究的主要发现和重大进展,如胶片生产和OSL读取器组装。本研究的目的是概述几个研究小组关于使用胶片或平板形式的OSLD进行1D和2D剂量映射的主要发现。最后,概述了使用OSLD胶片进行剂量映射的潜在未来发展。
