    5. Depth enhancement in spectral domain optical coherence tomography using bidirectional imaging modality with a single spectrometer

      Depth enhancement in spectral domain optical coherence tomography using bidirectional imaging modality with a single spectrometer
      A method for depth enhancement is presented using a bidirectional imaging modality for spectral domain optical coherence tomography (SD-OCT). Two precisely aligned sample arms along with two reference arms were utilized in the optical configuration to scan the samples. Using exemplary images of the optical resolution target, Scotch tape, a silicon sheet with two needles, and a leaf, we demonstrated how the developed bidirectional SD-OCT imaging method increases the ability ...

    7. Estimation of the flow resistances exerted in coronary arteries using a vessel length-based method

      Estimation of the flow resistances exerted in coronary arteries using a vessel length-based method
      Flow resistances exerted in the coronary arteries are the key parameters for the image-based computer simulation of coronary hemodynamics. The resistances depend on the anatomical characteristics of the coronary system. A simple and reliable estimation of the resistances is a compulsory procedure to compute the fractional flow reserve (FFR) of stenosed coronary arteries, an important clinical index of coronary artery disease. The cardiac muscle volume reconstructed from computed tomography (CT ...

    8. Recanalization of Organized Thrombi Demonstrated by Coronary CT Angiography Compared With OCT

      Recanalization of Organized Thrombi Demonstrated by Coronary CT Angiography Compared With OCT
      Recanalization of organized thrombi (ROT) is a rarely recognized disease histologically characterized by older coronary thrombi forming small lumens or endothelium-lined neovascular channels within thrombus. Optical coherence tomography (OCT) is the method of choice for diagnosis and shows signal-rich, high backscattered septa dividing the lumen into multiple small channels that communicate with each other (1) . Computed tomography angiography (CTA) in the longitudinal and cross-sectional planes may demonstrate the ROT by ...

      A Comparison of Intravascular Imaging Modalities for Detection of Stent Struts in Acute Coronary Syndrome
      Background We used optical coherence tomography (OCT) and intravascular ultrasound (IVUS) to assess the struts of implanted stents in patients with acute coronary syndrome (ACS). Methods A totle of 10,756 stent struts were analyzed with OCT in 42 patients of ACS. Of them, both of IVUS and OCT imaging were performed in 33 patients. Appearance of stent struts was classified as well apposed, buried, malapposed, and nondetectable, and the ...

    10. Wide-field optical coherence microscopy of the mouse brain slice

      Wide-field optical coherence microscopy of the mouse brain slice
      The imaging capability of optical coherence microscopy (OCM) has great potential to be used in neuroscience research because it is able to visualize anatomic features of brain tissue without labeling or external contrast agents. However, the field of view of OCM is still narrow, which dilutes the strength of OCM and limits its application. In this study, we present fully automated wide-field OCM for mosaic imaging of sliced mouse brains ...

  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
