Abstract

Optical coherence tomography (OCT) angiography is a well-established in vivo imaging technique to assess the overall vascular morphology of tissues and is an emerging field of research for the assessment of blood flow dynamics and functional parameters such as oxygen saturation. In this study, we present a modified scanning based correlation mapping OCT (cmOCT) using a 200 kHz high speed swept source OCT system operating at 1300 nm and demonstrate its wide field imaging capability in ocular angiographic studies.
