Quantitative depth resolved microcirculation imaging with optical coherence tomography angiography (Part Ι): Blood flow velocity imaging
The research goal of the microvascular network imaging with optical coherence tomography (OCT) angiography is to achieve depth resolved blood flow and vessel imaging in vivo in the clinical management of patents. In this review, we review the main phenomena that have been explored in OCT to image the blood flow velocity vector and the vessels of the microcirculation within living tissues. Parameters that limit the accurate measurements of blood flow velocity are then condisered. Finally, initial Clinic diagnosis applications of and future developments are discussed.
