  2. 1. Evaluation of a Laser Doppler System for Myocardial Perfusion Monitoring

    Author : Carina Fors; Karin Wårdell; Henrik Casimir Ahn; Maria Lindén; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser Doppler perfusion monitoring; myocardial microcirculation; coronary artery bypass graft; Medical engineering; Medicinsk teknik;

    Abstract : Coronary artery bypass graft (CABG) surgery is a common treatment for patients with coronary artery disease. A potential complication of CABG is myocardial ischemia or infarction. In this thesis, a method - based on laser Doppler flowmetry (LDF) - for detection of intra- and postoperative ischemia by myocardial perfusion monitoring is evaluated. READ MORE

  4. 2. Movement artifact reduction in laser Doppler blood flowmetry : myocardial perfusion applications

    Author : MG Daniel Karlsson; Karin Wårdell; Knut Kvernebo; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Laser Doppler perfusion monitoring (LDPM) and imaging (LDPI) enable assessment of tissue microvascular perfusion. The techniques are based on the Doppler broadening of the optical spectrum occurring when coherent laser light is scattered by moving red blood cells (RBC). READ MORE

  5. 3. Laser Doppler perfusion imaging : methodology and skin applications

    Author : Karin Wårdell; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Over the last decade a number of emerging technologies have become available for the non-invasive study of skin anatomy and physiology. In this thesis, a method for mapping tissue perfusion based on the laser Doppler technique is presented together with some of the associated experimental and clinical applications. READ MORE

  6. 4. Spatio-temporal filtering of ultrasound image sequences

    Author : Nina Eriksson-Bylund; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A number of diseases result in reduced perfusion of the vital organs of the body. Measures of the blood flow in the small vessels (the perfusion) of these organs would contribute significantly to a clinical diagnosis. Myocardial contrast echocardiography is a rapidly developing technique for non-invasive ultrasound imaging of perfusion. READ MORE

  7. 5. Pathophysiological and Histomorphological Effects of One-Lung Ventilation in the Porcine Lung

    Author : Alf Kozian; Göran Hedenstierna; Thomas Hachenberg; Filip Freden; Sten Walther; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alveolar Recruitment Manoeuvre; One-Lung Ventilation; Lung Protective Ventilation; Tidal Volume; Computed Tomography; Tidal Recruitment; Animal Model; Open Thoracic Surgery; Ventilation Perfusion Distribution; Single Photon Emission Computed Tomography; Diffuse Alveolar Damage; Medical laboratory science; Medicinsk laboratorievetenskap; Anestesiologi; Anaesthesiology;

    Abstract : Thoracic surgical procedures require partial or complete airway separation and the opportunity to exclude one lung from ventilation (one-lung ventilation, OLV). OLV is commonly associated with profound pathophysiological changes that may affect the postoperative outcome. READ MORE
