Review is made of dosimetric studies of current optical fibre technology in radiotherapy for therapeutic applications, focusing particularly on in vivo dosimetry for prostate radiotherapy. We present the various sensor designs along with the main advantages and disadvantages associated with this technology. Optical fibres are ideally placed for applications in radiotherapy dosimetry; due to their small size they are lightweight and immune to electromagnetic interferences. The small dimensions of optical fibres allows it to be easily guided within existing brachytherapy equipment; for example, within the seed implantation needle for direct tumour dose analysis, in the urinary catheter to monitor urethral dose, or within the biopsy needle holder of the transrectal ultrasound probe to monitor rectal wall dose. The article presents the range of optical fibre dosimeter designs along with the main dosimetric properties required for a modern in vivo dosimetry system to be utilised in a clinical environment.

光纤传感器：它们在前列腺癌放射治疗体内剂量测定中的作用。


对当前光纤技术在放射治疗中的剂量学研究进行了回顾，特别关注前列腺放射治疗的体内剂量学。我们介绍了各种传感器设计以及与该技术相关的主要优点和缺点。光纤非常适合放射治疗剂量测定应用；由于尺寸小，它们重量轻且不受电磁干扰。光纤的小尺寸使其能够在现有的近距离治疗设备中轻松引导；例如，在种子植入针内用于直接肿瘤剂量分析，在导尿管内用于监测尿道剂量，或在经直肠超声探头的活检持针器内用于监测直肠壁剂量。本文介绍了光纤剂量计的设计范围以及临床环境中使用的现代体内剂量测定系统所需的主要剂量测定特性。
