  Explore ScienceDirect Nov 21 2022 Ophthalmology
  
  Despite the rapid development of optical imaging methods, high-resolutioninvivoimaging with penetration into deeper tissue layers is still a major challenge. Optical coherence tomography (OCT) has been used successfully for non-invasive human retinal volumetric imaginginvivo, advancing the detection, diagnosis, and monitoring of various retinal diseases. However, there are important limitations of volumetric OCT imaging, especially coherent noise and the limited axial range over which high resolution images can be acquired. The ...

3. Towards retrieving dispersion profiles using quantum-mimic Optical Coherence Tomography and Machine Learning
  
  Explore arxiv.org Oct 27 2022
  
  Artefacts in quantum-mimic Optical Coherence Tomography are considered detrimental because they scramble the images even for the simplest objects. They are a side effect of autocorrelation which is used in the quantum entanglement mimicking algorithm behind this method. Interestingly, the autocorrelation imprints certain characteristics onto an artefact - it makes its shape and characteristics depend on the amount of dispersion exhibited by the layer that artefact corresponds to. This unique relationship ...

5. The use of optical coherence tomography for skin evaluation in healthy rats - A pilot study
  
  Explore Wiley Online Library Jun 4 2022 Dermatology
  
  Background: Noninvasive diagnostic techniques allow for morphological and morphometric in vivo evaluation of the skin. Optical coherence tomography (OCT) is a method that allows visualization of dermal structures up to several 100 m with a resolution of 3-7.5 m. Objectives: The aim of the study was the morphological and morphometric assessment of rats' skin using SD-OCT. Animals: Fifteen male Wistar rats, aged 3 and 8 months, weighing 350-450 g ...

6. Intraretinal Cysts as a Manifestation of Retinal Angiomatous Proliferation in Optical Coherence Tomography Angiography
  
  Explore MDPI Open Access Journals Platform May 30 2022 Ophthalmology
  
  Background and Objectives : Intraretinal cysts are common pathology observed inspectral domain optical coherence tomography (SDOCT) in patients with neovascular form of age-related macular degeneration (AMD). The aim of the study was to determine if the presence of intraretinal cysts is positively correlated with diagnosis of retinal angiomatous proliferation (RAP) in optical coherence tomography angiography (OCTA). Material and Methods : A total of 21 eyes with intraretinal cysts in SDOCT exam (Group1 ...

8. Multimode fiber as a tool to reduce cross talk in Fourier-domain full-field optical coherence tomography
  
  Explore Optica Publishing Group Feb 8 2022
  
  Fourier-domain full-field optical coherence tomography (FD-FF-OCT) is an emerging tool for high-speed eye imaging. However, cross-talk formation in images limits the imaging depth. To this end, we have recently shown that reducing spatial coherence with a fast deformable membrane can suppress the noise but over a limited axial range and with substantial data processing. Here, we demonstrate that a multimode fiber with carefully chosen parameters enables cross-talk-free imaging over a ...

  Explore OSA | OSA Publishing Jan 11 2022 Ophthalmology
  
  Several specialized retinal optical coherence tomography (OCT) acquisition and processing methods have been recently developed to allow in vivo probing of light-evoked photoreceptors function, focusing on measurements in individual photoreceptors (rods and cones). Recent OCT investigations in humans and experimental animals have shown that the outer segments in dark-adapted rods and cones elongate in response to the visible optical stimuli that bleach fractions of their visual photopigment. We have previously ...

11. Munch and optical coherence tomography: unravelling historical and artist applied varnish layers in painting collections
  
  Explore Home - Springer Sep 6 2021 Art
  
  Effective care of large-scale museum collections requires planning that includes the conservation treatment of specific groups of art works, such as appropriate cleaning strategies. Optical coherence tomography (OCT) has been successfully applied as a non-invasive method for the stratigraphic visualisation of the uppermost transparent and semi-transparent layers in paintings, such as varnishes. Several OCT case study examples have further demonstrated the capabilities of the non-contact interferometric technique to measure the ...

  Explore arxiv.org Jul 28 2021 Ophthalmology
  
  One of the greatest needs in modern ophthalmology is access to the eyes choroid in vivo. Without it, it is difficult to introduce new therapies and to understand most of the pathological changes in the eye, because 85% of the total blood flow in the eye i s caused by the choroidal circulation. It is entirely responsible for the metabolism of photoreceptors, which each of us feels every day and ...

  Explore OSA | OSA Publishing Apr 3 2021 Ophthalmology
  
  Whole eye visualization and morphometry are of high relevance in clinical practice. However, most standard ophthalmic OCT instruments are dedicated either to retinal or to anterior segment imaging. We demonstrate a swept source optical coherence tomography system (SS-OCT) that images both the whole anterior segment and the retina alternately using a single source and detector. A pilot population was imaged with the proof of concept prototype. We demonstrate the clinical ...

  Explore OSA | OSA Publishing Sep 28 2020
  
  Quantum optical coherence tomography (Q-OCT) is the non-classical counterpart of optical coherence tomography (OCT), a high-resolution 3D imaging technique based on white-light interferometry. Because Q-OCT uses a source of frequency-entangled photon pairs, not only is the axial resolution not affected by dispersion mismatch in the interferometer but is also inherently improved by a factor of two. Unfortunately, practical applications of Q-OCT are hindered by image-scrambling artefacts and slow acquisition times ...
