Title: Smarter Optical Coherence Tomography for Biomedical Applications

Optical coherence tomography (OCT) is a three-dimensional, high speed, high resolution imaging modality with a broad range of biomedical applications. For example, OCT has become a standard diagnostic device in clinical ophthalmology. Besides diagnosis, OCT also has great potential in surgical guidance. A miniature OCT probe based on fiber-optic components can be integrated with a conventional surgical instrument for hand-held scanning. Such small, light-weight OCT probe can offer surgeon with freedom to access imaging sites of interest with large field of view in limited space and thus provide real-time intraoperative imaging and sensing capability to enhance surgical outcome. In the past few years, my research focus has been the development of a hand-held OCT system for intraoperative applications. In this presentation, I will show a few examples of our research efforts for the development of intraoperative hand-held OCT. With my extensive experience in using OCT to interrogate various properties (physical/chemical) of specimen and processing the obtained information with sophisticated algorithm at a high speed, I plan to develop smarter OCT systems for biomedical applications here at Michigan Tech.

Biography: Dr. Liu received her B.S. and M.S. degrees from Tsinghua University, Beijing, China. She started to study in the Johns Hopkins University since 2007 and received her Ph.D degree in 2011. Before joining the faculty of Michigan Tech, Dr. Liu worked as post-doctoral fellow in the Johns Hopkins University.
