    2. Optical coherence tomography for rapid tissue screening and directed histological sectioning

      Optical coherence tomography for rapid tissue screening and directed histological sectioning
      In pathology, histological examination of the tissue is the “gold standard” to diagnose various diseases. It has contributed significantly toward identifying the abnormalities in tissues and cells, but has inherent drawbacks when used for fast and accurate diagnosis. These limitations include the lack of in vivo observation in real time and sampling errors due to limited number and area coverage of tissue sections. Its diagnostic yield also varies depending on the ability of the physician and the effectiveness of any image guidance technique that may be used for tissue screening during excisional biopsy. In order to overcome these current limitations ...

    3. Evaluation of caries-affected dentin with optical coherence tomography

      Evaluation of caries-affected dentin with optical coherence tomography
      The purpose of this study was to evaluate the degree of demineralization of artificially induced caries-affected human dentin by an in vitro microbiological method. The occlusal surfaces of 6 human molar teeth were abraded until a flat surface was obtained, and the enamel was removed to expose the occlusal dentin surface. These teeth were sectioned in 12 halves in the vestibular-lingual direction and divided into 3 groups according to the period length of the microbiological essay (n = 4): G1, 7 days; G2, 14 days; and G3, 21 days. The surfaces of all specimens were protected by an acid-resistant nail varnish ...

    4. Interferometric Synthetic Aperture Microscopy (ISAM) Reconstruction and Characterization In A High Numerical Aperture System (Thesis)

      Interferometric Synthetic Aperture Microscopy (ISAM) Reconstruction and Characterization In A High Numerical Aperture System (Thesis)
      Optical coherence microscopy (OCM) is an imaging modality that is capable of visualizing structural features of biological samples at high resolution based on their scattering properties. Interferometric synthetic aperture microscopy (ISAM) is a newer technique that can overcome the typical dependence between lateral resolution and depth-of-focus of an optical coherence tomography (OCT) imaging system by offering spatially invariant resolution within the whole 3D data set, including regions that are outside of the focal region. Both OCM and ISAM have many potential research and clinical applications. By combining OCM and ISAM, it is possible to visualize an entire 3D volumetric data ...

    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).
      In Fujimoto Honored with Britton Chance Biomedical Optics Award
    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.
