    5. Effect of Optic Disc Tilt on the Measurement of Peripapillary Vessel Density Using Optical Coherence Tomography Angiography

      Effect of Optic Disc Tilt on the Measurement of Peripapillary Vessel Density Using Optical Coherence Tomography Angiography
      Precis: Eyes with tilted disc had significantly lower peripapillary vessel density (pVD) and lower long-term measurement reproducibility in OCTA. After adjusting for confounding factors, disc tilt still contributed to the reduction of pVD in most sectors. Purpose: To investigate the effect of optic disc tilt on the measurement of sectoral peripapillary vessel density (pVD) by optical coherence tomography angiography (OCTA) and on the long-term measurement reproducibility.

    11. Combined Use of Multiple Intravascular Imaging Techniques in Acute Coronary Syndrome

      Combined Use of Multiple Intravascular Imaging Techniques in Acute Coronary Syndrome
      Recent advances in intravascular imaging techniques have made it possible to assess the culprit lesions of acute coronary syndrome (ACS) in the clinical setting. Intravascular ultrasound (IVUS) is the most commonly used intravascular imaging technique that provides cross-sectional images of coronary arteries. IVUS can assess plaque burden and vessel remodeling. Optical coherence tomography (OCT) is a high-resolution (10 m) intravascular imaging technique that uses near-infrared light. OCT can identify key ...

    15. Optical Coherence Tomography Angiography Findings of Macular Choriovitreal Membrane Secondary to Spontaneous Closure of Traumatic Macular Hole

      Optical Coherence Tomography Angiography Findings of Macular Choriovitreal Membrane Secondary to Spontaneous Closure of Traumatic Macular Hole
      ear Editor, Since traumatic macular hole (TMH) was first described in 1869, there have been hypotheses to explain its pathophysiology and MH closure. Previously suggested mechanisms for macular hole (MH) closure were glial or retinal pigment epithelium (RPE) cell proliferation [ 1 ], contraction of the epiretinal membrane or operculum around the edge [ 2 , 3 ]. Recently, we experienced a spontaneously closed TMH accompanied by macular choriovitreal membrane (MCVM) formation in a young ...

      Vision-Inspection-Synchronized Dual Optical Coherence Tomography for High-Resolution Real-Time Multidimensional Defect Tracking in Optical Thin Film Industry
      Large-scale product inspection is an important aspect in thin film industry to identify defects with a high precision. Although vision line scan camera (VLSC)-based inspection has been frequently implemented, it is limited to surface inspections. Therefore, to overcome the conventional drawbacks, there is a need to extend inspection capabilities to internal structures. Considering that VLSC systems have access to rich information, such as color and texture, high-resolution real-time multimodal ...

  2. About University of Ulsan

    University of Ulsan

    University of Ulsan was founded on February 19, 1969 as the Ulsan Institute of Technology. The University was promoted to a fully-fledged University on March 1, 1985. Located in Mu-guh dong (i.e., Mu-gah neighborhood) within Ulsan, South Korea, the University currently enrolls approximately 10,500 students. The city of Ulsan has been recognized as the Korean city which was built around the corporate base of the multinational Hyundai conglomerate. Thus, the Hyundai Conglomerate announced its plan to give 40 billion won to assist a variety of university-industry cooperation projects. This corporate relationship has helped turn the University into one of South Korea's top rated institutions for graduate job placement, as well as increasing its reputation more broadly as one of the top private universities outside of Seoul
