    2. The feasibility and utility of optical coherence tomography directed histopathology for surgical margin assessment of canine mast cell tumors

      The feasibility and utility of optical coherence tomography directed histopathology for surgical margin assessment of canine mast cell tumors
      Histopathologic surgical margin assessment in veterinary patients is an imprecise science with assessment limited to a small proportion of the surgical margin due to time and finances. Incomplete excision of canine mast cell tumors (MCTs) alters treatment recommendations and prognosis. Optical coherence tomography (OCT) is a novel imaging modality that has been reported in a single veterinary study for surgical margin assessment. Twenty‐five dogs with 34 MCTs were enrolled ...

    4. Cone Photoreceptor Integrity assessed with Adaptive Optics Imaging after Laser-Pointer-Induced Retinal Injury

      Cone Photoreceptor Integrity assessed with Adaptive Optics Imaging after Laser-Pointer-Induced Retinal Injury
      Purpose: To examine the three-dimensional foveal cone photoreceptor structure in a patient who had suffered laser pointer induced retinal injury . Methods: Patient underwent standard fundus photography and clinical spectral domain optical coherence tomography (SD-OCT) imaging. High-resolution imaging was performed using an Adaptive Optics -OCT-Scanning Laser Ophthalmoscope (AO-OCT-SLO). Results: AO imaging revealed loss of inner and outer segments of cone photoreceptors while the anterior retinal layers appeared healthy. Analysis of cone ...

    5. Near‐infrared imaging and optical coherence tomography for intraoperative visualization of tumors

      Near‐infrared imaging and optical coherence tomography for intraoperative visualization of tumors
      Surgical excision is the foundation of treatment for early‐stage solid tumors in man and companion animals. Complete excision with appropriate margins of surrounding tumor‐free tissue is crucial to survival. Intraoperative imaging allows real‐time visualization of tumors, assessment of surgical margins, and, potentially, lymph nodes and satellite metastatic lesions, allowing surgeons to perform complete tumor resections while sparing surrounding vital anatomic structures. This Review will focus on the ...

    6. A marine biofilm flow cell for in situ screening marine fouling control coatings using optical coherence tomography

      A marine biofilm flow cell for in situ screening marine fouling control coatings using optical coherence tomography
      A novel fouling marine flow cell was designed and fitted with a clear plastic lid to allow real-time imaging of biofilms using optical coherence tomography (OCT). Marine biofilms were grown under controlled shear flow on coupons coated with 6 different biocidal antifouling coatings (SPC1, SPC2, SPC3, SPC4, CDP1 and CDP2, AkzoNobel) and one inert coating which contained no biocidal actives (NB-D) for 8 weeks. One set of coupons coated with ...

    7. Inner Retinal Changes in Primary Open-Angle Glaucoma Revealed Through Adaptive Optics-Optical Coherence Tomography

      Inner Retinal Changes in Primary Open-Angle Glaucoma Revealed Through Adaptive Optics-Optical Coherence Tomography
      Purpose: To examine the microstructural changes in the inner nuclear layer (INL) and ganglion cell layer (GCL) in a primary open-angle glaucoma (POAG) subject at 2 timepoints, 4 months apart. Patients and Methods: This case-control study (1 POAG subject and 1 normal control) used the single cell, 3-dimensional volumetric imaging capability of an adaptive optics - optical coherence tomography -scanning laser ophthalmoscopy system to examine the inner retina. Results: At the ...

    9. Polarization Variability in Age-related Macular Degeneration

      Polarization Variability in Age-related Macular Degeneration
      SIGNIFICANCE Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss. Complementary imaging techniques can be used to better characterize and quantify pathological changes associated with AMD. By assessing specific light-tissue interactions, polarization-sensitive imaging can be used to detect tissue disruption early in the disease process. PURPOSE The aim of this study was to compare variability in central macular polarization properties in patients with nonexudative AMD and age-matched ...

    10. Volumetric imaging of rod and cone photoreceptor structure with a combined adaptive optics-optical coherence tomography-scanning laser ophthalmoscope

      Volumetric imaging of rod and cone photoreceptor structure with a combined adaptive optics-optical coherence tomography-scanning laser ophthalmoscope
      We have designed and implemented a dual-mode adaptive optics (AO) imaging system that combines spectral domain optical coherence tomography (OCT) and scanning laser ophthalmoscopy (SLO) for in vivo imaging of the human retina. The system simultaneously acquires SLO frames and OCT B-scans at 60 Hz with an OCT volume acquisition time of 4.2 s. Transverse eye motion measured from the SLO is used to register the OCT B-scans to ...

    11. Early lung cancer detection, mucosal, and alveolar imaging

      Early lung cancer detection, mucosal, and alveolar imaging
      Purpose of review: Lung cancer is the leading cause of cancer deaths worldwide. Early detection is essential for long-term survival. Screening of high-risk individuals with low-dose computed tomography screening has proven to increase survival. However, current radiological imaging techniques have poor specificity for lung cancer detection and poor sensitivity for detection of mucosal or alveolar preinvasive malignant lesions. Bronchoscopy allows imaging and sampling of early lung cancer, with the highest ...

    13. Segmentation of microcystic macular edema in Cirrus OCT scans with an exploratory longitudinal study

      Segmentation of microcystic macular edema in Cirrus OCT scans with an exploratory longitudinal study
      Microcystic macular edema (MME) is a term used to describe pseudocystic spaces in the inner nuclear layer (INL) of the human retina. It has been noted in multiple sclerosis (MS) as well as a variety of other diseases. The processes that lead to MME formation and their change over time have yet to be explained sufficiently. The low rate at which MME occurs within such diverse patient groups makes the ...

      Performance of a combined optical coherence tomography and scanning laser ophthalmoscope with adaptive optics for human retinal imaging application
      We describe the design and performance of a recently implemented retinal imaging system for the human eye that combines adaptive optics (AO) with spectral domain optical coherence tomography (OCT) and scanning laser ophthalmoscopy (SLO). The AO-OCT-SLO system simultaneously acquires SLO frames and OCT B-scans at 60 Hz with an OCT volume acquisition scan rate of 0.24 Hz. The SLO images are used to correct for eye motion during the ...
