Title: Recent Advances of Optical Coherence Tomography in Biomedical Imaging Applications
Speaker: Prof. Ruikang Wang, Department of Bioengineering and Ophthalmology, University of Washington
Abstract
Optical coherence tomography (OCT) is a new medical imaging modality in which the coherent interference of a wide spectrum light source is used to create a high resolution (micron-scale) subsurface image of tissue microstructure. Recently, we have supplemented the microstructural OCT images with additional contrast mechanisms such as blood flow imaging using the static and dynamic (Doppler) speckle effects, which provide us the ability to perform label-free optical microangiography (OMAG) of microcirculatory tissue beds. The ability to visualize tissue blood flow at the microcirculation level is important in a variety of biomedical applications, some of which (along with the OCT basics and the enabling technologies) will be highlighted in this talk. Examples using OCT and OMAG to delineate tissue microanatomy, dynamic blood perfusion, down to capillary level resolution, within living tissue will be given, including ocular, oral and skin tissue organs in humans.
