The automatic three dimensional segmentation method is used to obtain seven surfaces of intra-retinal layers. The microvascular network of the retina, which is acquired by the IBDV method, can be divided into six layers. The microvascular network of the six individual layers are visualized, and the morphology and contrast images can be improved by using ...

      Assessment of corneal viscoelasticity using elastic wave optical coherence elastography
      The corneal viscoelasticity have great clinical significance, such as the early diagnosis of keratoconus. In this work, an analysis method which utilized the elastic wave velocity, frequency and energy attenuation to assess the corneal viscoelasticity is presented. Using phase‐resolved optical coherence tomography, the spatial‐temporal displacement map is derived. The phase velocity dispersion curve and center frequency are obtained by transforming the displacement map into the wavenumber‐frequency domain ...

    4. In vivo evaluation of corneal biomechanical properties by optical coherence elastography at different cross-linking irradiances

      In vivo evaluation of corneal biomechanical properties by optical coherence elastography at different cross-linking irradiances
      Corneal collagen cross-linking (CXL) strengthens the biomechanical properties of damaged corneas. Quantifying the changes of stiffness due to different CXL protocols is difficult, especially in vivo . A noninvasive elastic wave-based optical coherence elastography system was developed to construct in vivo corneal elasticity maps by excitation of air puff. Biomechanical differences were compared for rabbit corneas given three different CXL protocols while keeping the total energy delivered constant. The Youngs modulus ...

    9. Semi-Supervised Automatic Segmentation of Layer and Fluid Region in Retinal Optical Coherence Tomography Images Using Adversarial Learning

      Semi-Supervised Automatic Segmentation of Layer and Fluid Region in Retinal Optical Coherence Tomography Images Using Adversarial Learning
      Optical coherence tomography (OCT) is a primary imaging technique for ophthalmic diagnosis due to its advantages in high resolution and non-invasiveness. Diabetes is a chronic disease, which could cause retinal layer deformation and fluid accumulation. It might increase the risk of blindness, and thus, it is important to monitor the morphology change of the retinal layer and fluid accumulation for diabetes patients. Due to the existence of deformation and fluid ...

      Integrating Handcrafted and Deep Features for Optical Coherence Tomography Based Retinal Disease Classification
      Deep Neural Networks (DNNs) have been widely applied to automatic analysis of medical images for disease diagnosis, and to help human experts by efficiently processing immense amounts of images. While handcrafted feature has been used for eye disease detection or classification since the 1990s, DNN was recently adopted in this area and showed very promising performance. Since handcrafted and deep feature can extract complementary information, we propose in this paper ...

  2. About Wenzhou Medical College

    Wenzhou Medical College

    Wenzhou Medical College, designated as a key university in Zhejiang, is an institution of higher learning under the leadership of Zhejiang Provincial Government. Its history can be traced back to Zhejiang Specialized Medical School established in Hangzhou in 1912, named "Zhejiang Second Medical College" at that time. In August 1958, part of Zhejiang Medical College was moved from Hangzhou to Wenzhou and began recruiting 5-year fulltime program students, hence the name Wenzhou Medical College (WMC).
