5. Neural network-based image reconstruction in swept-source optical coherence tomography using undersampled spectral data
  
  Explore Home - IEEE Photonics Society Mar 13 2021
  
  Optical Coherence Tomography (OCT) is a widely used non-invasive biomedical imaging modality that can rapidly provide volumetric images of samples. Here, we present a deep learning-based image reconstruction framework that can generate swept-source OCT (SS-OCT) images using undersampled spectral data, without any spatial aliasing artifacts. This neural network-based image reconstruction does not require any hardware changes to the optical set- up and can be easily integrated with existing swept-source or ...

9. Optical Coherence Tomography Angiography of the Choriocapillaris in Age-Related Macular Degeneration
  
  Explore MDPI Open Access Journals Platform Feb 22 2021 Ophthalmology
  
  The advent of optical coherence tomography angiography (OCTA) has allowed for remarkable advancements in our understanding of the role of the choriocapillaris in age-related macular degeneration (AMD). As a relatively new imaging modality, techniques to analyze and quantify choriocapillaris images are still evolving. Quantification of the choriocapillaris requires careful consideration of many factors, including the type of OCTA device, segmentation of the choriocapillaris slab, image processing techniques, and thresholding method ...

  Retinal imaging technology is rapidly advancing and can provide ever-increasing amounts of information about the structure, function and molecular composition of retinal tissue in humans in vivo . Most importantly, this information can be obtained rapidly, non-invasively and in many cases using Food and Drug Administration-approved devices that are commercially available. Technologies such as optical coherence tomography have dramatically changed our understanding of retinal disease and in many cases have significantly ...

12. Automated Retinal Vein Cannulation on Silicone Phantoms using Optical Coherence Tomography-Guided Robotic Manipulations
  
  Explore IEEE Xplore Jan 5 2021 Ophthalmology
  
  Retinal vein occlusion is one of the most common causes of vision loss, occurring when a blood clot or other obstruction occludes a retinal vein. A potential remedy for retinal vein occlusion is retinal vein cannulation, a surgical procedure that involves infusing the occluded vein with a fibrinolytic drug to restore blood flow through the vascular lumen. This work presents an image-guided robotic system capable of performing fully automated cannulation ...
