Medical imaging using on-chip THz waveguides

该项目将开发新的成像模式，用于使用太赫兹光进行医学成像，包括自由空间和导波系统。具体来说，将开发用于扫描成像的芯片上谐振太赫兹电路，其中由于癌变组织和非癌变组织之间太赫兹介电常数的差异，会出现对比度。我们还将研究商用太赫兹相机在开发简单太赫兹成像系统中的使用，用于成像/绘制手术场景。组织幻影将首先作为手术环境的替身，而最终目标是将芯片/成像系统整合到现有的内窥镜探针中。实验工作将通过使用商业高频软件（包括HFSS）进行全3D建模来验证和理解。这项工作将与该领域正在进行的EPSRC计划补助金联系起来。

The project will develop new imaging modalities for medical imaging using THz light to include both free space and guided wave systems. Specifically, resonant on-chip THz circuits will be developed for scanned imaging in which contrast will appear caused by differences in THz permittivity between cancerous and non-cancerous tissue. We will also investigate the use of commercial THz cameras in developing simple THz imaging systems for use in imaging / mapping a surgical scene. Tissue phantoms will be developed to act as a stand in for the surgical environment in the first instance, while the eventual goal is incorporation of the chips/ imaging system into an existing endoscopic probe. Experimental work will be validated and understood with the aid of full 3D modelling performed using commercial high frequency software (including HFSS). The work will link in with an ongoing EPSRC Programme Grant in this area.
