New Paper From Roorda Lab

Several researchers from the Roorda Lab, including Fabio Feroldi, Sanam Mozaffari, Francesco LaRocca, Pavan Tiruveedhula, Austin Roorda, and their team (Patrick D. Gregory, B. Hyle Park), had a new paper published in the Biomedical Optics Express Journal, titled: "Retinal imaging using adaptive optics optical coherence tomography with fast and accurate real-time tracking." The journal selected their paper as "Editor's Pick!" Congratulations to the Roorda Lab researchers!

Read the abstract below:

"One of the main obstacles in high-resolution 3-D retinal imaging is eye motion, which causes blur and distortion artifacts that require extensive post-processing to be corrected. Here, an adaptive optics optical coherence tomography (AOOCT) system with real-time active eye motion correction is presented. Correction of ocular aberrations and of retinal motion is provided by an adaptive optics scanning laser ophthalmoscope (AOSLO) that is optically and electronically combined with the AOOCT system. We describe the system design and quantify its performance. The AOOCT system features an independent focus adjustment that allows focusing on different retinal layers while maintaining the AOSLO focus on the photoreceptor mosaic for high fidelity active motion correction. The use of a high-quality reference frame for eye tracking increases revisitation accuracy between successive imaging sessions, allowing to collect several volumes from the same area. This system enables spatially targeted retinal imaging as well as volume averaging over multiple imaging sessions with minimal correction of motion in post processing."
