    2. Assessment of early occlusal caries pre- and post- sealant application—An imaging approach

      Assessment of early occlusal caries pre- and post- sealant application—An imaging approach

      Background and Objective Clinicians have difficulty assessing and monitoring early occlusal caries. Traditional clinical exam and radiographs are unable to detect the subtle alterations in enamel indicative of de- or re-mineralization, particularly under dental sealants. Although clinicians have used laser fluorescence (LF) to address this gap, this modality has demonstrated weak correlation with histology. The International Caries Detection and Assessment System (ICDAS-II) has demonstrated high sensitivity and specificity for caries detection, but since it is based on visual assessment, it is of no use in areas beneath the most commonly used dental sealants which are opaque. Optical coherence tomography (OCT ...

    5. Expanding OCT: Quanitifying the Cornea’s Optical Performance

      Expanding OCT: Quanitifying the Cornea’s Optical Performance

      Optical coherence tomography, a well-known method for imaging the retina, may allow physicians to perform quantitative metrology of the eye’s own optics. Swept-source OCT allows for simultaneous imaging of the cornea, iris and retina in living patients. Laser refractive surgeries such as laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) have brought better vision to tens of millions worldwide. But these techniques also exact a cost: because they work by reshaping the eye’s cornea, they make accurate measurement of the cornea’s optical parameters after surgery unreliable using conventional tools. That’s important, not only because inaccurate ...

    7. Adaptive replanning intensity-modulated radiotherapy for choroidal metastasis of breast cancer using optical coherence tomography

      Adaptive replanning intensity-modulated radiotherapy for choroidal metastasis of breast cancer using optical coherence tomography

      Swept source optical coherence tomography (SS-OCT) is a convenient method for precise, early-stage detection of choroidal metastatic lesions, involving assessment of tumor response, and for regular follow-up studies. Using information obtained with SS-OCT, we performed intensity-modulated radiotherapy (IMRT) for a patient with choroidal metastasis from breast cancer with more accuracy than had been previously possible. We made replanning adaptive radiotherapy (ART) three times based on the rapid tumor shrinkage detected by weekly assessments with SS-OCT. Accordingly, the planning target volume (PTV) decreased from 1.6 cm 3 to 0.61 cm 3 (38%), with 0.95 cm 3 (59%) and ...

    10. Spatial Heterogeneity of Neoatherosclerosis, and its Relationship with Neovascularization and Adjacent Plaque Characteristics: Optical Coherence Tomography Study

      Spatial Heterogeneity of Neoatherosclerosis, and its Relationship with Neovascularization and Adjacent Plaque Characteristics: Optical Coherence Tomography Study

      Background Development of neoatherosclerosis (NA) has been reported to be a potential cause of late stent failure. However, the distribution of NA and its relationship with neovascularization (NV) and adjacent plaque characteristics remain unclear. Methods We investigated 167 stents (40 bare-metal stents, 84 sirolimus-eluting stents, and 43 everolimus-eluting stents) with optical coherence tomography. Each stent was divided into the proximal section (PS), mid section (MS) and distal section (DS). NA was defined as lipid-laden neointima or calcification inside stent. Adjacent plaque characteristics were evaluated within 5 mm proximal and distal reference segments. Results NA was more frequent in PS and ...

      Eric Swanson discusses the migration of optical coherence tomography (OCT) into clinical practice in, "Clinical Translation in OCT: Role of Research, Funding, and Entrepreneurism." The translation from research to successful clinical impact is challenging and often the process passes through several stages including product development, initial sales and product iteration, market growth, and, finally, the next generation products. Each step can take several years, requiring persistence and perseverance on the parts of technologists and investors alike. The first release of a reliable, manufacturable, and supportable commercial product into the hands of clinicians is a critical milestone. It allows for fine ...
