    3. Integrated IVUS-OCT for Real-Time Imaging of Coronary Atherosclerosis

      Integrated IVUS-OCT for Real-Time Imaging of Coronary Atherosclerosis

      Accurate assessment of atherosclerotic plaque characteristics and the subsequent tailoring of optimal therapy holds great promise for preventing acute coronary syndromes (ACS) and life-threatening sequelae 1 . Combined use of optical coherence tomography (OCT) and intravascular ultrasound (IVUS) was proposed as a potential method for accurate assessment of plaque characteristics and vulnerability ( 2 , ). However, significant challenges remain in trying to adapt an integrated OCT-IVUS system for clinical applications. We report here a fully integrated intracoronary OCT-IVUS imaging technique to visualize atherosclerotic plaque in living animals and human coronary arteries from cadavers with high resolution and deep penetration capability simultaneously.

    4. Grading of posterior staphyloma with spectral-domain optical coherence tomography and correlation with macular disease

      Grading of posterior staphyloma with spectral-domain optical coherence tomography and correlation with macular disease

      OBJECTIVE: To develop a novel grading system for posterior staphyloma imaged by spectral-domain optical coherence tomography (SD-OCT) and to correlate the incidence of macular disease (vitreomacular traction, epiretinal membrane, macular schisis, lamellar macular hole, and full-thickness macular hole) with each grade. DESIGN: Retrospective chart review. PARTICIPANTS: A total of 150 eyes from 89 patients with posterior staphylomas were examined at Jules Stein Eye Institute, University of California Los Angeles. METHODS: Retrospective analysis of the Cirrus SD-OCT (Carl Zeiss Meditec, Dublin, Calif.) database at a large institution (Jules Stein Eye Institute) was performed and eyes with a posterior staphyloma involving the ...

      Optical coherence tomography 2014

      Optical coherence tomography (OCT) is now widely recognized as the most important retinal imaging technique, replacing angiographic techniques as first-line imaging tools. This has largely been driven by widespread application of retinal pharmacotherapy. As a clinical decision-making tool in that setting, OCT has unparalleled value in delivering important information in a matter of seconds. OCT has dramatically improved the productivity of retinal specialists — ie, the number of patients who can be evaluated in a given clinical session. This special issue on OCT highlights its value as a quantitative tool in assessing retinal anatomy in both health and disease, its power ...

    6. Feature Of The Week 11/24/13 : Miniature OCT/IVUS probe for automatically co-registered three-dimensional intracoronary imaging with real-time display

      Feature Of The Week 11/24/13 : Miniature OCT/IVUS probe for automatically co-registered three-dimensional intracoronary imaging with real-time display

      Combined use of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) holds the potential of combining the strengths of both imaging modalities and improving the diagnostic accuracy of atherosclerotic plaque vulnerability. In this manuscript, we reported a co-registered intracoronary OCT-IVUS system and catheter with real-time imaging and polar-coordinate displaying capability, well-suited for clinical utilization in guiding interventional cardiologists. With an eventual goal of clinical use in humans, this novel catheter design and modified software are poised to strengthen the ability to diagnose vulnerable plaques in patients in real-time. We upgraded our old designs in the following aspects. 1) This novel ...

    8. Absolute retinal blood flow measurement with a dual-beam Doppler optical coherence tomography

      Absolute retinal blood flow measurement with a dual-beam Doppler optical coherence tomography

      Purpose:To test the capability of a novel dual-beam Doppler optical coherence tomography (OCT) technique for simultaneous in vivo measurement of the Doppler angle and, thus, the absolute retinal blood velocity and the retinal flow rate, without the influence of motion artifacts. Methods:A novel dual-beam Doppler spectral domain OCT (SD-OCT) was developed. The two probing beams are separated with a controllable distance along an arbitrary direction, both of which are controlled by two independent 2D optical scanners. Two sets of optical Doppler tomography (ODT) images are acquired simultaneously. The Doppler angle of each blood vessel segment was calculated from ...

  2. About University of Southern California

    University of Southern California

    University of Southern California is located in Los Angeles, a global center for arts, technology and international trade and is one of the world’s leading private research universities. USC enrolls more international students than any other U.S. university and offers extensive opportunities for internships and study abroad. With a strong tradition of integrating liberal and professional education, USC fosters a vibrant culture of public service and encourages students to cross academic as well as geographic boundaries in their pursuit of knowledge. The Keck School of Medicine is the medical school at the University of Southern California. Founded in 1885 as the USC College of Medicine, it was closed in 1921 and reopened in 1928 as the USC School of Medicine.
