  1. 1. Right heart function in health and disease : a doppler echocardiography and doppler tissue imaging study

    Author : Per Lindqvist; Elsadig E Kazzam; Anders Waldenström; Lars Åke Brodin; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler tissue imaging; right ventricle; cardiac catheterisation; isovolumic relaxation; isovolumic contraction; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Abstract : Background: It is well known that performance of the right ventricle (RV) determines exercise capacity and may confer prognostic information in different cardiopulmonary diseases. To allow optimal patient management, ideal methods to assess right heart function are therefore important. READ MORE

  2. 2. Laser Doppler Flowmetry and Imaging: Methodological Studies

    Author : Siv Bornmyr; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital photography.; cold intolerance; sympathetic nervous system; flow cessation external pressure; skin temperature; thermography; skin blood flow; laser doppler imaging; Laser doppler flowmetry; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Laser Doppler flowmetry (LDF) and laser Doppler imaging (LDI) are modern methods for non-invasive and continuous assessment of skin blood flow. The techniques are based on the phenomenon that monochromatic light transilluminating a perfused tissue is spectrally broadened owing to scattering by moving blood cells. READ MORE

  3. 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

  4. 4. Doppler tissue imaging in ST-elevation myocardial infarction

    Author : Nils Witt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Highly available, noninvasive and cost-effective, echocardiography remains a keystone in the evaluation of patients with coronary artery disease (CAD). Echocardiographic assessment of cardiac function at rest and during dobutamine stress has direct clinical implications. READ MORE

  5. 5. On the use of light for the characterization and treatment of malignant tumours

    Author : Claes af Klinteberg; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Diffusion equation; Aminolevulinic acid; Protoporphyrin IX; Photodynamic therapy; Fluorescence spectroscopy; Fluorescence imaging; Laser-Doppler perfusion imaging; Atom- och molekylärfysik; Atomic and molecular physics; Multiple scattering; Tissue optics; Tissue optical properties; Fysicumarkivet A:1999:Klinteberg;

    Abstract : Some aspects on the use of light for tissue characterization and treatment of malignant tumours are discussed within this thesis. The work presented aims at improving optical techniques for tissue characterization, especially to detect malignant and pre-malignant lesions. READ MORE
