    2. 3D shadow reduction signal processing method for optical coherence tomography (OCT) images

      3D shadow reduction signal processing method for optical coherence tomography (OCT) images
      Shadows caused by opacities and obstructions (such as blood vessels) can block detection of structural information of objects below the shadow-causing structure, affecting visualization and analysis of those deeper structures. An image processing method for removing these shadows includes applying a low pass filter to an energy profile of an image to remove high frequency fluctuations in energy, thereby effectively recovering lower energy inside shadow regions and removing high frequency ...

    5. Evaluation of morning glory syndrome by swept-source optical coherence tomography

      Evaluation of morning glory syndrome by swept-source optical coherence tomography
      Purpose: To investigate the deep structural abnormalities in the patients with morning glory syndrome by using swept-source optical coherence tomography (swept-source OCT). Methods: The papillary and peripapillary areas of the 4 eyes (4 patients) with morning glory syndrome were examined with a prototype swept-source OCT system with a center wavelength of 1050 nm. Particularly, the abnormalities of the lamina cribrosa as well as peripapillary sclera were evaluated. Results: The lamina ...

    7. Image quality improvement methods for optical coherence tomography

      Image quality improvement methods for optical coherence tomography
      Ophthalmological images generated by coherent imaging modalities have multiple types of noise, including random noise caused by the imaging system and speckle noise caused by turbid objects such as living tissues. These noises can occur at different levels in different locations. A noise-reduction method and system of the present disclosure thus relates to applying different filters for different types of noise and/or different locations of images, sequentially or in ...
