Abstract
In this study we present a desktop swept-source optical coherence tomographic angiography (OCTA) system for a diverse range of ophthalmic applications. The system can achieve 500 kHz ultrafast imaging with a 75-degree field of view, assisted by a GPU-accelerated real-time cross-sectional and en face OCT/OCTA acquisition interface, a self-tracking method for motion correction, and an AI-based retinal layer segmentation algorithm. High-resolution and high-sensitivity OCTA images from different retinal disease types are demonstrated.
