Fibre Optic Dosimeters for Medical and Environmental Applications

我们将开发用于环境监测和放射治疗的光纤剂量计。一种使用折射率梯度的新方法将被用来捕捉闪烁体光，同时抑制噪声。我们将对闪烁体和玻璃的辐射损伤机制有新的认识。这种小巧、灵活、准确的光纤剂量计将在吸收特性方面与人体组织等同，使其优于目前所有可用的剂量计。光纤剂量计将使新的自适应放射治疗技术成为可能，并为放射治疗中的剂量传递提供质量保证。它们的多路复用能力将导致在工作场所和航空航天环境监测方面的应用。

We will develop fibre optic dosimeters for environmental monitoring and radiation therapy. A novel approach using refractive index gradients will be used to capture scintillator light while rejecting noise. New knowledge will be gained of the mechanisms of radiation damage in scintillators and glasses. The small, flexible, accurate fibre optic dosimeters will be equivalent in absorbing characteristics to human tissue, making them superior to all currently available dosimeters. Fibre optic dosimeters will enable new adaptive radiotherapy techniques and provide quality assurance of dose delivery in radiotherapy. Their multiplexing capability will lead to applications in monitoring of workplaces and aerospace environments.
