Abstract

We implemented a real-time video-rate 4D-OCT system with virtual reality display. To achieve the required low latencies we optimized the dataflow path and the placement of the necessary synchronization points. Employing temporal reprojection enables to perform volume rendering at 1/3 of the display refresh rate, yet maintaining smooth updates to the HMD; thus we achieve display updates at 90Hz, volume rendering at 30Hz and C-scan acquisition at <15Hz. By mounting of a tracking accessory to the scanning head we can render the OCT volume in virtual space in the position of the actual imaging volume.
