      Economical and compact briefcase spectral-domain optical coherence tomography system for primary care and point-of-care applications
      Development of low-cost and portable optical coherence tomography (OCT) systems is of global interest in the OCT research community. Such systems enable utility broadly throughout a clinical facility, or in remote areas that often lack clinical infrastructure. We report the development and validation of a low-cost, portable briefcase spectral-domain optical coherence tomography (SD-OCT) system for point-of-care diagnostics in primary care centers and/or in remote settings. The self-contained briefcase OCT ...

      Wavefront measurement using computational adaptive optics
      In many optical imaging applications, it is necessary to correct for aberrations to obtain high quality images. Optical coherence tomography (OCT) provides access to the amplitude and phase of the backscattered optical field for three-dimensional (3D) imaging samples. Computational adaptive optics (CAO) modifies the phase of the OCT data in the spatial frequency domain to correct optical aberrations without using a deformable mirror, as is commonly done in hardware-based adaptive ...

      Review of optical coherence tomography in oncology
      The application of optical coherence tomography (OCT) in the field of oncology has been prospering over the past decade. OCT imaging has been used to image a broad spectrum of malignancies, including those arising in the breast, brain, bladder, the gastrointestinal, respiratory, and reproductive tracts, the skin, and oral cavity, among others. OCT imaging has initially been applied for guiding biopsies, for intraoperatively evaluating tumor margins and lymph nodes, and ...

      Noninvasive in vivo optical coherence tomography tracking of chronic otitis media in pediatric subjects after surgical intervention
      In an institutional review board-approved study, 25 pediatric subjects diagnosed with chronic or recurrent otitis media were observed over a period of six months with optical coherence tomography (OCT). Subjects were followed throughout their treatment at the initial patient evaluation and preoperative consultation, surgery (intraoperative imaging), and postoperative follow-up, followed by an additional six months of records-based observation. At each time point, the tympanic membrane (at the light reflex region ...

    14. Investigating the healing mechanisms of an angiogenesis-promoting topical treatment for diabetic wounds using multimodal microscopy

      Investigating the healing mechanisms of an angiogenesis-promoting topical treatment for diabetic wounds using multimodal microscopy
      Impaired skin wound healing is a significant co-morbid condition of diabetes that is caused by poor microcirculation, among other factors. Studies have shown that angiogenesis, a critical step in the wound healing process in diabetic wounds, can be promoted under hypoxia. In this study, an angiogenesis-promoting topical treatment for diabetic wounds, which promotes angiogenesis by mimicking a hypoxic environment via inhibition of prolyl hydroxylase resulting in elevation or maintenance of ...

    2. We agree that, given the images we've seen from the hardware [adaptive optics] systems, our computational approaches are equivalent to those...In addition, we think we could do better by correcting the finer aberrations and by being able to manipulate the data post-acquisition, which gives us a lot more flexibility.

    5. 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.

    6. 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.
