Abstract

We present a microscope-integrated Optical Coherence Tomography (OCT) system for aiding ophthalmic surgical manoeuvers. It generates two B-scans dynamically locked on the tip of the surgical tool to provide relevant depth cues. The low-latency architecture of our tool-tracking engine provides a position update rate of 200 Hz in a bid to minimize instantaneous tool position tracking errors. Likewise, the B-scan update rate of 200 Hz helps reduce motion artefacts while allowing for high signal-to-noise ratio averaged OCT images displayed at 50 Hz.
