Abstract

Point-scan swept-source optical coherence tomography systems (SS-OCTs) are subject to volumetric framerate limits governed by source sweep rate and scanner dynamics. For scenes with dynamic features on static backgrounds, adaptive scanning escapes these limits by visiting scan positions only as needed. We implemented adaptive scanning using a probabilistic approach that balanced re-imaging of known dynamic positions with exploration for undiscovered ones. We evaluated our approach in model systems that simulated ophthalmic surgery and multi-target tracking using a 200 kHz SS-OCT system. We demonstrated framerate speedups of 6.7x and 8.0x, respectively, performance that would have otherwise required a significantly faster source.
