  1. 1. Usefulness of coronary angiography for assessing left ventricular function

    Författare :Anders Kähäri; Bertil Svane; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis focus on the physiological information, on left ventricular (LV) motion in the long axis, evaluated in routine coronaty angiography sequences and based on previous knowledge from echocardiographic studies. As coronary angiography has become a very frequent examination, a method for assessment of LV function from routine coronary angiograms would probably have a significant impact on clinical work.

  3. 2. Controlled growth of hexagonal GaN pyramids and InGaN QDs

    Författare :Anders Lundskog; Erik Janzén; Urban Forsberg; Per-Olof Holtz; Lars-Erik Wernersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Gallium-nitride (GaN) and its related alloys are direct band gap semiconductors, with a wide variety of applications. The white light emitting diode (LED) is of particular importance as it is expected to replace energy inefficient light bulb and hazardous incandescent lamps used today. LÄS MER

  4. 3. Noninvasive Evaluation of Myocardial Ischemia and Left Ventricular Function

    Författare :Eva Maret; Jan Ohlsson; Eva Nylander; Anders Waldenström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The general aim of this thesis was, following the path of the ischemic cascade, to evaluate the feasibility of some new non-invasive techniques for the detection of myocardial ischemia, the extent of infarcted myocardium, and for the quantification of systolic left ventricular function.Reduced longitudinal myocardial velocity and displacement may be early signs of ischemia.

  5. 4. Magnetic Resonance Imaging of Myocardial Deformation and Scarring in Coronary Artery Disease

    Författare :Johan Kihlberg; Jan Engvall; Tino Ebbers; Anders Persson; Åse Johnsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Although improved treatments have reduced the rates of acute complications from myocardial infarction, sequelae such as heart failure and sudden death threaten the future wellbeing of those patients. Secondary prevention after myocardial infarction is related to cardiovascular risk factors and the effect of the infarct on left ventricular function. LÄS MER

  7. 5. Goal Function Approach to Growth and Remodeling of Arteries

    Författare :Ganarupan Satha; Anders Klarbring; Stefan B. Lindström; Jonas Stålhand; Håkan Johansson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis we develop a new goal function approach to investigate stability of the growth processes in blood vessels and cost-optimal composition and geometry of these vessels. In the vascular system of a healthy individual, the living composition of the arterial wall must regenerate and remodel continuously during the entire lifetime to maintain itself. LÄS MER
