      Development of high-speed, integrated high-resolution optical coherence microscopy and dual-channel fluorescence microscopy for the simultaneous co-registration of reflectance and fluorescence signals
      Optical coherence microscopy is an imaging technique capable of generating three-dimensional images of structures in tissue, but with limited functional imaging ability. Fluorescence microscopy offers functional information of cellular activities. The integration of both imaging modalities can enable the evaluation of the impact of structural information on cells activities. To develop an integrated system combining high-resolution optical coherence microscopy (HR-OCM) and dual-channel scanning confocal fluorescence microscopy (DC-SCFM) to enable the ...

    3. Cross-Polarization Optical Coherence Tomographic Assessment of In situ Simulated Erosive Tooth Wear

      Explore Wiley Online Library Dentistry
      Cross-Polarization Optical Coherence Tomographic Assessment of In situ Simulated Erosive Tooth Wear
      This clinical study tested cross-polarization optical coherence tomography (CP-OCT) monitoring of erosive tooth wear (ETW). Twenty participants completed a 14-day/arm, 3-arm crossover study simulating different ETW severities. Participants received two enamel specimens (per arm) and were randomized to: severe (s-ETW, lemon juice/pH:2.5/4.25%w/v citric acid), moderate (m-ETW, grapefruit juice/pH:3.5/1.03%w/v citric acid), and non-ETW (water). Enamel thickness ...

      Weakly supervised individual ganglion cell segmentation from adaptive optics OCT images for glaucomatous damage assessment
      Cell-level quantitative features of retinal ganglion cells (GCs) are potentially important biomarkers for improved diagnosis and treatment monitoring of neurodegenerative diseases such as glaucoma, Parkinsons disease, and Alzheimers disease. Yet, due to limited resolution, individual GCs cannot be visualized by commonly used ophthalmic imaging systems, including optical coherence tomography (OCT), and assessment is limited to gross layer thickness analysis. Adaptive optics OCT (AO-OCT) enables in vivo imaging of individual retinal ...

      Phase II multi-center trial of optical coherence tomography as an adjunct to white light cystoscopy for intravesical real time imaging and staging of bladder cancer
      Background: Optical coherence tomography (OCT) is a novel imaging modality that provides microstructural information of different tissue layers using near-infrared light. This prospective, multicenter phase II trial aimed to assess the accuracy of OCT-assisted cystoscopy for bladder tumor staging. Methods: Patients with primary or recurrent bladder tumors (Ta,T1) identified by outpatient cystoscopy were included. The primary objective was to assess the accuracy and positive predictive value of for determining ...

      Detection and analyzing plane of non-cavitated approximal caries by cross-polarized optical coherence tomography (CP-OCT)
      Objective: The objective was to assess the detection ability and the effect of analyzing plane of CP-OCT for non-cavitated approximal caries. Methods: Thirty human extracted premolars were selected based on micro-computed tomography [-CT: - CT = 0: sound (n = 12), -CT = 1/2: caries into outer-/inner-half of enamel (n = 6 each), -CT = 3: caries into outer one-third of dentine (n = 6)]. Teeth were mounted in a custommade device to simulate approximal ...

    7. Multi-reference global registration of individual A-lines in adaptive optics optical coherence tomography retinal images

      Explore SPIE Digital Library Ophthalmology
      Multi-reference global registration of individual A-lines in adaptive optics optical coherence tomography retinal images
      Significance: Adaptive optics optical coherence tomography (AO-OCT) technology enables non-invasive, high-resolution three-dimensional (3D) imaging of the retina and promises earlier detection of ocular disease. However, AO-OCT data are corrupted by eye-movement artifacts that must be removed in post-processing, a process rendered time-consuming by the immense quantity of data. Aim: To efficiently remove eye-movement artifacts at the level of individual A-lines, including those present in any individual reference volume. Approach: We ...

      Cellular Scale Imaging of Transparent Retinal Structures and Processes Using Adaptive Optics Optical Coherence Tomography
      High-resolution retinal imaging is revolutionizing how scientists and clinicians study the retina on the cellular scale. Its exquisite sensitivity enables time-lapse optical biopsies that capture minute changes in the structure and physiological processes of cells in the living eye. This information is increasingly used to detect disease onset and monitor disease progression during early stages, raising the possibility of personalized eye care. Powerful high-resolution imaging tools have been in development ...

      Optic nerve head diurnal vessel density variations in glaucoma and ocular hypertension measured by optical coherence tomography angiography
      Background/aims To evaluate diurnal variations in optic nerve head (ONH) vessel density assessed by optical coherence tomography angiography (OCT-A) in healthy subjects, ocular hypertension (OHT), and open-angle glaucoma (OAG) patients. Methods Forty subjects (OAG, 21; OHT, 6; healthy, 13) were assessed for vessel density percentage (VD%) and flow index in the ONH (NH VD%, NH index), and in the radial peripapillary capillary layer (RPC VD%, RPC index) at 9 ...

      Quantitative assessment of human donor corneal endothelium with Gabor domain optical coherence microscopy
      We report on a pathway for Gabor domain optical coherence microscopy (GD-OCM)-based metrology to assess the donors corneal endothelial layers ex vivo . Six corneas from the Lions Eye Bank at Albany and Rochester were imaged with GD-OCM. The raw 3-D images of the curved corneas were flattened using custom software to enhance the 2-D visualization of endothelial cells (ECs); then the ECs within a circle of 500-m-diameter were analyzed ...
