In Vivo Quantitative Analysis of Anterior Chamber White Blood Cell Mixture Composition Using Spectroscopic Optical Coherence Tomography
Ruobing Qian, Ryan P. McNabb, Kevin C. Zhou +5
Anterior uveitis is the most common form of intraocular inflammation, and one of its main signs is the presence of white blood cells (WBCs) in the anterior chamber (AC). Clinically…
Mesoscopic photogrammetry with an unstabilized phone camera
Kevin C. Zhou, Colin Cooke, Jaehee Park +4
We present a feature-free photogrammetric technique that enables quantitative 3D mesoscopic (mm-scale height variation) imaging with tens-of-micron accuracy from sequences of image…
Unified k-space theory of optical coherence tomography
Kevin C. Zhou, Ruobing Qian, Al-Hafeez Dhalla +2
We present a general theory of optical coherence tomography (OCT), which synthesizes the fundamental concepts and implementations of OCT under a common 3D k-space framework. At the…
Video-rate high-precision time-frequency multiplexed 3D coherent ranging
Ruobing Qian, Kevin C. Zhou, Jingkai Zhang +3
Recently, there has been growing interest and effort in developing high-speed high-precision 3D imaging technologies for a wide range of industrial, automotive and biomedical appli…
Toward Autonomous Robotic Micro-Suturing using Optical Coherence Tomography Calibration and Path Planning
Yuan Tian, Mark Draelos, Gao Tang +4
Robotic automation has the potential to assist human surgeons in performing suturing tasks in microsurgery, and in order to do so a robot must be able to guide a needle with sub-mi…
