Wednesday, October 16, 2019
12:00 pm - 1:00 pm
Dr. Yali Jia, Associate Professor of Ophthalmology & Biomedical Engineering, School of Medicine, Jennie P. Weeks Professor of Ophthalmology, Oregon Health & Science University

Optical coherence tomography (OCT) is a powerful ophthalmic imaging modality. Recently OCT structural imaging has been supplemented by two key technologies that provide for additional imaging functionality. In OCT angiography the intrinsic motion contrast provided by blood flow allow visualization of retinal vasculature at capillary-scale detail. I will introduce most recent advances achieved by our group in this area, including our exploration on high-efficient, real-time, wide-field, motion-free OCT angiography, and our experience on overcoming artifacts using artificial intelligence-based algorithms. In OCT oximetry the absorption contrast between oxygenated and deoxygenated hemoglobin is used to measure oxygen saturation within retinal blood vessels. I will discuss our recent work on the development and validation of OCT oximetry measurement using visible-light OCT on rodent models.
