  4. Distance From the Coronary Ostium as a Predictor of Vulnerable Plaque Morphology; An In-vivo Optical Coherence Tomography Study

    Explore Article Circulation (Nov 10 2008) Cardiology

    Background: Plaque morphology predicts its vulnerability to cause acute coronary events; most of which occur due to disruption of lipid-rich thin-cap fibroatheroma (TCFA). Observational studies show that lesions causing acute events are clustered in the proximal coronary artery segments. Aim: To evaluate whether the location of plaque in the coronary vessel is predictive of vulnerable plaque morphology identified by optical coherence tomography (OCT). Methods: OCT was performed in patients undergoing ... (Read Full Article)

  5. Imaging system and related techniques

    Explore Article PatFT » Page 1 of 1 (Nov 4 2008) Patents

    BACKGROUND OF THE INVENTION As is known in the art, fiber optic endoscopy is typically conducted by transmitting an image through an array of fibers often referred to as a fiber bundle. While successful for a variety of medical and non-medical applications, utilization of an array of fibers to form the image imposes constraints on the cost, diameter, and flexibility of the imaging device. In an attempt to overcome these ... (Read Full Article)
