Abstract
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. For example, 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 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, including probe
fabrication, motion artifact correction and novel algorithms for OCT signal processing.
