    2. Comparison of a MEMS-Based Handheld OCT Scanner With a Commercial Desktop OCT System for Retinal Evaluation

      Comparison of a MEMS-Based Handheld OCT Scanner With a Commercial Desktop OCT System for Retinal Evaluation

      Purpose: The goal of this study was to evaluate the ability of our handheld optical coherence tomography (OCT) scanner to image the posterior and anterior structures of the human eye, and especially the individual layers of the retina, and to compare its diagnostic performance with that of a fixed desktop commercial ophthalmic OCT system. Methods: We compared the clinical imaging results of our handheld OCT with a leading commercial desktop ophthalmic system (RTVue) used in specialist offices. Six patients exhibiting diabetes-related retinal pathology had both eyes imaged with each OCT system. Results: In both sets of images, the structural irregularities ...

      Computational adaptive optics for interferometric synthetic aperture microscopy and other interferometric imaging

      Methods for correcting for aberrations in the image or three-dimensional reconstruction of a sampled region obtained by broadband interferometry. The sampled region is illuminated with a broadband beam of light, and light returned from the sample is detected, along with a reference beam, in order to derive an interference signal for pixels of a volume spanned by wavenumber and axes transverse to the beam propagation direction. An optimization procedure is performed with respect to a specified criterion so as to obtain an aberration-corrected image of at least one plane of the sampled region, either in a plane-specific manner or in ...

    6. Segmentation And Correlation Of Optical Coherence Tomography And X-RAY Images For Breast Cancer Diagnostics.

      Segmentation And Correlation Of Optical Coherence Tomography And X-RAY Images For Breast Cancer Diagnostics.

      Pre-operative X-ray mammography and intraoperative X-ray specimen radiography are routinely used to identify breast cancer pathology. Recent advances in optical coherence tomography (OCT) have enabled its use for the intraoperative assessment of surgical margins during breast cancer surgery. While each modality offers distinct contrast of normal and pathological features, there is an essential need to correlate image -based features between the two modalities to take advantage of the diagnostic capabilities of each technique. We compare OCT to X-ray images of resected human breast tissue and correlate different tissue features between modalities for future use in real-time intraoperative OCT imaging . X-ray ...

    7. State of the Industry report on Optical Coherence Tomography

      State of the Industry report on Optical Coherence Tomography

      The first commercial optical coherence tomography (OCT) imagers were introduced to ophthalmology by Advanced Ophthalmic Devices (now owned by Zeiss Meditec) in 1992. Since then, the market for OCT systems has grown at an impressive compounded annual rate of about 45%. This segment of the biophotonics marketplace has flourished because OCT enables sub-surface imaging of translucent or opaque materials, such as human tissue, in real time at micron resolution and without the use of ionizing radiation. As a result, last year’s global sales of all OCT systems exceeded $400 million and the market now supports more than 36 OCT ...

    1. Jim's innovation, scholarly activities, professional service, entrepreneurial efforts, and impact on the field of biomedical optics typifies the spirit of this award, and reflects the seminal changes that Britton Chance made during his lifetime...Few researchers in the world today have had such a profound impact as a result of their technological work that has literally changed our field, changed the way we practice medicine, and directly improved the lives of perhaps hundreds of thousands of patients (considering ophthalmology and cardiology).

    2. We know that antibiotics don’t always work well if you have a biofilm, because the bacteria protect themselves and become resistant...In the presence of a chronic ear infection that has a biofilm, the bacteria may not respond to the usual antibiotics, and you need to stop them. But without being able to detect the biofilm, we have no idea whether or not it’s responding to treatment.

    3. I think it's going to dramatically change things...What we hope is that diagnosis is going to get shifted closer and closer to the point of care...We’re developing techniques to get at molecular changes..So much of medicine and pathology are based on structural changes. If we think of a pathologist looking at a slide, he or she looks at the cells and tissue structures. A radiologist will look at how organs and these anatomical structures are arranged...But with a lot of these techniques, we can get the molecular changes where disease starts. So a pathologist that has molecular information, not just structural, will perhaps catch disease earlier. The same is true for Rohit’s work and Gabi’s work.

    5. The effectiveness is striking...Because of the aberrations of the human eye, when you look at the retina without adaptive optics you just see variations of light and dark areas that represent the rods and cones. But when you use adaptive optics, you see the rods and cones as distinct objects...are working to compute the best image possible.
