    1. Optical coherence tomography in multiple sclerosis: A 3-year prospective multicenter study

      Optical coherence tomography in multiple sclerosis: A 3-year prospective multicenter study

      Objective: To evaluate changes over 3 years in the thickness of inner retinal layers including the peripapillary retinal nerve fiber layer (pRNFL), and combined macular ganglion cell and inner plexiform layers (mGCIPL), in individuals with relapsing-remitting multiple sclerosis (RRMS) versus healthy controls; to determine whether optical coherence tomography (OCT) is sufficiently sensitive and reproducible to detect small degrees of neuroaxonal loss over time that correlate with changes in brain volume and disability progression as measured by the Expanded Disability Status Scale (EDSS). Methods: Individuals with RRMS from 28 centers (n = 333) were matched with 64 healthy participants. OCT scans were ...

    2. Instructor in Optical Coherence Tomography (OCT) in the Tearney Laboratory

      Instructor in Optical Coherence Tomography (OCT) in the Tearney Laboratory

      The Tearney Laboratory at the Wellman Center for Photomedicine, Massachusetts General Hospital, is recruiting for Instructor faculty position at Harvard Medical School. The Tearney Lab pioneers the invention, development, and translation of new noninvasive, high-resolution optical imaging modalities that enable disease diagnosis from living patients without excising tissues from the body. One of the most powerful such technologies is optical coherence tomography (OCT) that captures cross-sectional and three-dimensional microscopic images of tissue. We are seeking a motivated researcher to join our team to play a direct role in advancing our research and scientific agenda. The Instructor will work in a ...

    4. 105° field of view non-contact handheld swept-source optical coherence tomography

      105° field of view non-contact handheld swept-source optical coherence tomography

      We demonstrate a handheld swept-source optical coherence tomography (OCT) system with a 400 kHz vertical-cavity surface-emitting laser (VCSEL) light source, a non-contact approach, and an unprecedented single shot 105° field of view (FOV). We also implemented a spiral scanning pattern allowing real-time visualization with improved scanning efficiency. To the best of our knowledge, this is the widest FOV achieved in a portable non-contact OCT retinal imaging system to date. Improvements to the FOV may aid the evaluation of retinal diseases such as retinopathy of prematurity, where important vitreoretinal changes often occur in the peripheral retina.

    5. Peer-to-peer technology is very useful for developers of SS-OCT systems

      Peer-to-peer technology is very useful for developers of SS-OCT systems

      Peer-to-peer streaming is a crucial feature for data acquisition boards used in swept-source OCT (SS-OCT). Learn more about the underlying technology that helps achieve high-speed data transfers at 7 Gbyte/s to graphical processing units (GPUs), and helps significantly improve digitizer system's performance. P2P streaming side-tracks the host PC by enabling direct data transfers between the digitizer and graphics processing units (GPUs) or to storage. This is a huge advantage compared to conventional solutions which require data to be copied via the RAM of the host PC. With peer-to-peer, both the CPU and RAM can instead be used for ...

    6. Robotically aligned optical coherence tomography with 5 degree of freedom eye tracking for subject motion and gaze compensation

      Robotically aligned optical coherence tomography with 5 degree of freedom eye tracking for subject motion and gaze compensation

      Optical coherence tomography (OCT) has revolutionized diagnostics in ophthalmology. However, OCT requires a trained operator and patient cooperation to carefully align a scanner with the subject’s eye and orient it in such a way that it images a desired region of interest at the retina. With the goal of automating this process of orienting and aligning the scanner, we developed a robot-mounted OCT scanner that automatically aligned with the pupil while matching its optical axis with the target region of interest at the retina. The system used two 3D cameras for face tracking and three high-resolution 2D cameras for ...

      Postdoc Position at the University of Southern California

      A postdoctoral researcher position is available immediately in the Keck School of Medicine. The successful candidate will work on highly collaborative projects for functional imaging with Optical Coherence Tomography. The collaboration includes researchers in the departments of Otolaryngology (John Oghalai, MD), Ophthalmology (Narsing Rao, MD, Mark Humayun, MD,PhD), and Biomedical Engineering (Scott Fraser, PhD, Qifa Zhou, PhD). The projects involve the development of highly phase-stable optical systems for human in vivo imaging of nanoscale vibrations in the ear, blood flow in the inner ear and blood flow deep in the eye’s choroidal vasculature. There is also opportunity to ...
