Abstract

Most of current OCT-based angiography suffers from small FOV with short imaging range. Here we implement an ultralong-range OCT system for vascular imaging based on an akinetic swept source. This swept-source OCT (SS-OCT) system enables us to achieve up to 46 mm long imaging range with unprecedented roll-off performance. To compare with traditional spectral domain OCT (SD-OCT) system, we demonstrated the vascular imaging of the entire mice brain with wide FOV by this ultralong-range SS-OCT system and captured the blood flow images at different depth position, which shows the great advantages and bright future of this ultralong-range SS-OCT in vascular imaging.
