我们将腔增强吸收传感的精密工具应用于临床肿瘤学，展示了一种以厘米级体积水作为组织等效传感介质的剂量计范式。该概念验证全光学方案实现了临床放疗脉冲的实时读出，标称单脉冲分辨率为90 μGy。此项演示为开发光纤集成、微米级设备以用于治疗期间的原位通用绝对剂量测定铺平了道路。
英文摘要
We apply the precision tools of cavity-enhanced absorption sensing to clinical oncology, demonstrating a dosimeter paradigm in which a centimeter-scale volume of water serves as a tissue-equivalent sensing medium. Our proof-of-concept, all-optical scheme achieves real-time readout of clinical radiation pulses with a nominal single-pulse resolution of 90 $μ$Gy. This demonstration paves the way toward fiber-integrated, micron-scale devices for $\textit{in situ}$ universal absolute dosimetry during treatment.
