报告题目:Intelligent optical coherence tomography for structural and functional imaging(智能光学相干层析技术:结构和功能成像)



报告人:刘璇教授, 新泽西理工学院

Abstract: Optical coherence tomography (OCT) is a cross-sectional imaging modality based on low coherence light interferometry. With microscopic resolution and fast imaging speed, OCT has been used in ophthalmology, interventional cardiology and many other biomedical fields. Liu’s lab (Biophotonics imaging and sensing laboratory) at New Jersey Institute of Technology (NJIT) focuses on developing intelligent OCT technologies, enabled by high speed data acquisition and processing, advanced algorithms for signal analysis, and in-house capability for the design and fabrication of novel fiber-optic imaging instruments. This presentation will provide a brief overview on the principle of OCT as well as several contrast mechanisms of OCT imaging, and will discuss research endeavor at Liu’s lab on structural and functional OCT imaging for applications such as cancer diagnosis, traumatic brain injury research, and sensor guided surgical treatment. 

报告摘要:光学相干断层成像 optical coherence tomography, OCT)是一种利用低相干光干涉仪进行层析成像的技术。实时显微成像的OCT技术在眼科诊断,介入性心血管疾病治疗,以及其他生物医学领域有着广泛应用。新泽西理工学院电子工程系生物光学成像与传感实验室具备高速OCT信号采集和处理能力,开发了多种先进的信号处理算法,并在光学探头设计和制造方便有着丰富的经验。在此基础上,刘璇博士带领的团队致力于研发智能OCT技术。本报告将简要介绍OCT系统原理和几种成像机制,以及OCT在癌症诊断,脑创伤研究和手术导航方面的应用。 

Bio: Xuan Liu received her B.S. and M.S. degrees from Tsinghua University. She came to the U.S. for her Ph.D. study and received her Ph.D. degree in Electrical Engineering from the Johns Hopkins University in 2011.
