2. A Joint Model for Macular Edema Analysis in Optical Coherence Tomography Images Based on Image Enhancement and Segmentation
  
  Explore Hindawi Publishing Corporation Feb 23 2021 Ophthalmology
  
  Optical coherence tomography (OCT) provides the visualization of macular edema which can assist ophthalmologists in the diagnosis of ocular diseases. Macular edema is a major cause of vision loss in patients with retinal vein occlusion (RVO). However, manual delineation of macular edema is a laborious and time-consuming task. This study proposes a joint model for automatic delineation of macular edema in OCT images. This model consists of two steps: image ...

3. Axial and horizontal registration guided speckle suppression in single-line HD mode for retinal optical coherence tomography images
  
  Explore ScienceDirect Jan 29 2021 Ophthalmology
  
  We propose an image registration method to suppress the speckle noise in retinal optical coherence tomography(OCT) adapted to single-line HD mode hardware implementation. In single-line HD mode, multiple cross-section images at the same straight scan line are obtained repeatedly and rapidly for averaging the speckle noise. Not like static objects, cross-section retinal images are often blurred by direct averaging due to unintentional eye/head motions in axial and horizontal ...

4. Semi-Supervised Capsule cGAN for Speckle Noise Reduction in Retinal OCT Images
  
  Explore IEEE Xplore Jan 7 2021 Ophthalmology
  
  Speckle noise is the main cause of poor optical coherence tomography (OCT) image quality. Convolutional neural networks (CNNs) have shown remarkable performances for speckle noise reduction. However, speckle noise denoising still meets great challenges because the deep learning-based methods need a large amount of labeled data whose acquisition is time-consuming or expensive. Besides, many CNNs-based methods design complex structure based networks with lots of parameters to improve the denoising performance ...

  AIM To investigate changes in macular vessels and thickness in myopic eyes after intraocular collamer lens (ICL) implantation using quantitative optical coherence tomography angiography (OCTA). METHODS This retrospective included 73 myopic eyes of 73 patients (average age, 27.536.16y) who underwent ICL implantation (28 eyes were Toric ICL). Axial length (AL), uncorrected visual acuity (UCVA), refractive dioptre (RD), intraocular pressure (IOP) and OCTA were measured and compared with before ...

6. Quantitative Analysis of Macular Retina Using Light Reflection Indices Derived from SD-OCT for Pituitary Adenoma
  
  Explore Hindawi Publishing Corporation Nov 20 2020 Ophthalmology
  
  Purpose: To quantitatively investigate the macular retinal light reflection characteristic using optical property indices derived from spectral-domain optical coherence tomography (SD-OCT) scans with depth attenuation compensation for pituitary adenoma. Methods: This study included 38 patients (mean age 44.66 13.77 years old) with diagnosis of pituitary adenoma and 43 age-matched controls. All SD-OCT scans were light attenuation compensated by a depth-resolved model. Attenuation coefficient, the corrected intensity, and the ...

7. AGE challenge: Angle Closure Glaucoma Evaluation in Anterior Segment Optical Coherence Tomography
  
  Explore ScienceDirect Sep 13 2020 Ophthalmology
  
  Angle closure glaucoma (ACG) is a more aggressive disease than open-angle glaucoma, where the abnormal anatomical structures of the anterior chamber angle (ACA) may cause an elevated intraocular pressure and gradually lead to glaucomatous optic neuropathy and eventually to visual impairment and blindness. Anterior Segment Optical Coherence Tomography (AS-OCT) imaging provides a fast and contactless way to discriminate angle closure from open angle. Although many medical image analysis algorithms have ...

8. Low Tensor Train- and Low Multilinear Rank Approximationsfor De-speckling and Compression of 3D Optical Coherence Tomography Images
  
  Explore arxiv.org Sep 2 2020
  
  This paper proposes low tensor-train (TT) rank and low multilinear (ML) rank approximations for de-speckling and compression of 3D optical coherence tomography (OCT) images for a given compression ratio (CR). To this end, we derive the alternating direction method of multipliers based algorithms for the related problems constrained with the low TT- and low ML rank. Rank constraints are implemented through the Schatten-p (Sp) norm, p e {0, 1/2 ...

  Purpose : To segment and quantify three distinct retinal capillary plexuses using optical coherence tomography angiography (OCTA) in myopic eyes. Methods : We analyzed 96 eyes from 62 subjects with myopia (27.76 7.05 years of age) and evaluated 30 normal eyes from 15 subjects (28.33 3.13 years of age) for controls. En face OCTA images generated by AngioPlex (Carl Zeiss; Oberkochen, Germany) were manually segmented by the progressive ...

11. Dual-side view optical coherence tomography for thickness measurement on opaque materials
  
  Explore OSA | OSA Publishing Feb 15 2020 NDE/NDT
  
  Optical coherence tomography (OCT), as an optical interferometric imaging technique, has found wide applications in various fields. In principle, OCT is well suited for imaging layered structures, and thus, one of the typical applications is thickness measurement. However, due to the limited imaging depth resulting from light attenuation, thickness measurement by OCT is limited to non-opaque materials. In this study, we developed a novel (to the best of our knowledge ...

12. Segmentation Guided Registration for 3D Spectral-Domain Optical Coherence Tomography Images
  
  Explore IEEE Xplore Nov 5 2019 Ophthalmology
  
  Medical image registration can be used for combining information from multiple imaging modalities, monitoring changes in size, shape or image intensity over time intervals. However, the development of such technique can be challenging for 3D spectral-domain optical coherence tomography (SD-OCT) imaging, because SD-OCT image is inherently noisy and its high resolution leads to high complexity of non-rigid registration. In this paper, a new segmentation guided approach is reported for registration ...

  The combination of optical coherence tomography (OCT) and endoscope can take images of the body tissues for clinical diagnosis. OCT images are difficult to photograph with regular imaging devices, such as the esophagus and gastrointestinal tract. Three-dimensional reconstruction of the two-dimensional sequence images can help the doctor understand the clinical situation of the body tissue, therefore improve the accuracy of diagnosis. In this paper, Ray Casting method is used to ...

  Speckle is a major quality degrading factor in optical coherence tomography (OCT) images. In this work we propose a new deep learning network for speckle reduction in retinal OCT images, termed DeSpecNet. Unlike traditional algorithms, the model can learn from training data instead of manually selecting parameters such as noise level. The proposed deep convolutional neural network (CNN) applies strategies including residual learning, shortcut connection, batch normalization and leaky rectified ...
