    2. Assessment of Coronary Artery Lesion Using Optical Coherence Tomography Versus IntraVascular Ultrasound for BiorEsorbable Vascular Scaffold Implantation

      Assessment of Coronary Artery Lesion Using Optical Coherence Tomography Versus IntraVascular Ultrasound for BiorEsorbable Vascular Scaffold Implantation
      The primary objective is to determine whether IVUS- (vs. OCT-) guided BVS implantation is non-inferior to achieve a large in-scaffold minimal lumen area (primary endpoint) measured by OCT at 1-year follow-up.

    3. 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 ...

    4. 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 ...

    5. A Comparison of Intravascular Imaging Modalities for Detection of Stent Struts in Acute Coronary Syndrome

      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 ...

    6. 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 ...

    7. Incidence and Clinical Significance of Poststent Optical Coherence Tomography Findings: One-Year Follow-Up Study From a Multicenter Registry

      Incidence and Clinical Significance of Poststent Optical Coherence Tomography Findings: One-Year Follow-Up Study From a Multicenter Registry
      Background Optical coherence tomography (OCT) was recently introduced to optimize percutaneous coronary intervention. However, the exact incidence and significance of poststent OCT findings are unknown. Methods and Results A total of 900 lesions treated with 1001 stents in 786 patients who had postprocedure OCT imaging were analyzed to evaluate the incidence of poststent OCT findings and to identify the OCT predictors for device-oriented clinical end points, including cardiac death, target ...

      Objectives The aim of this study was to define the morphological features of coronary artery spasm sites using optical coherence tomography (OCT) in patients with vasospastic angina (VSA). Background Plaque characteristics at coronary artery spasm sites have not been investigated systematically. Methods Sixty-nine consecutive patients (80 spasm sites) presenting with VSA who underwent OCT imaging were included in this study. Fibrous cap disruption was identified by the discontinuation of fibrous ...

      Purpose : To evaluate the value of lamina cribrosa (LC)-related parameters assessed by optical coherence tomography (OCT) in the future prediction of glaucomatous progression. Methods : Glaucoma or glaucoma suspect eyes were followed up for more than 2 years. Glaucoma progression was defined by optic disc/retinal nerve fiber layer (RNFL) photographic assessment or serial visual field exams. LC thickness, anterior LC distance (ALD) and prelaminar tissue thicknesses were determined with ...

      Comparison of Neoatherosclerosis and Neovascularization Between Patients With and Without Diabetes : An Optical Coherence Tomography Study
      Objectives This study aimed to investigate the characteristics of neoatherosclerosis (NA) in patients with diabetes mellitus (DM) after drug-eluting stent (DES) implantation using optical coherence tomography. Background NA is an important substrate for stent failure. In vivo NA characteristics in DM patients have not been investigated. Methods A total of 397 patients with 452 DES who underwent follow-up optical coherence tomography examination after DES implantation were enrolled. Characteristics of NA ...

      Optical coherence tomography for the diagnosis and evaluation of human otitis media
      We report the application of optical coherence tomography (OCT) to the diagnosis and evaluation of otitis media (OM). Whereas conventional diagnostic modalities for OM, including standard and pneumatic otoscopy, are limited to visualizing the surface of the tympanic membrane (TM), OCT effectively reveals the depth-resolved microstructure below the TM with very high spatial resolution, with the potential advantage of its use for diagnosing different types of OM. We examined the ...

    13. Optical Coherence Tomographic Observation of In-Stent Neoatherosclerosis in Lesions With More Than 50% Neointimal Area Stenosis After Second-Generation Drug-Elnuting Stent Implantation

      Optical Coherence Tomographic Observation of In-Stent Neoatherosclerosis in Lesions With More Than 50% Neointimal Area Stenosis After Second-Generation Drug-Elnuting Stent Implantation
      Background Despite the enhanced properties of the second-generation drug-eluting stent (DES), its association with neoatherosclerosis has not been sufficiently evaluated. Therefore, we sought to evaluate and compare neoatherosclerosis in second-generation DESs to first-generation DESs. Methods and Results A total of 212 DES-treated patients with 50% percent neointimal cross-sectional area stenosis were retrospectively enrolled from the Korean multicenter optical coherence tomography (OCT) registry. Within this population, 111 patients had a second-generation ...

      A Hierarchical Cluster Analysis of Normal-Tension Glaucoma Using Spectral-Domain Optical Coherence Tomography Parameters
      Purpose: Normal-tension glaucoma (NTG) is a heterogenous disease, and there is still controversy about subclassifications of this disorder. On the basis of spectral-domain optical coherence tomography (SD-OCT), we subdivided NTG with hierarchical cluster analysis using optic nerve head (ONH) parameters and retinal nerve fiber layer (RNFL) thicknesses. Patients and Methods: A total of 200 eyes of 200 NTG patients between March 2011 and June 2012 underwent SD-OCT scans to measure ...

  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
