  2. 11. The Non-Invasive Brain Biopsy : Implementation and Application of Quantitative Magnetic Resonance Spectroscopy on Healthy and Diseased Human Brain

    Author : Anders Tisell; Peter Lundberg; Marcel Warntjes; Anne-Marie Landtblom; Örjan Smedby; Jan Weis; Linköpings universitet; []
    Keywords : ;

    Abstract : Introduction: In this thesis, one of the major objectives was to implement a method for (absolute) quantitative magnetic resonance spectroscopy (qMRS) of the human brain, intended for clinical use. The implemented method was based on standard spatially selective MRS sequences. READ MORE

  4. 12. Influence of optical properties on Laser Doppler Flowmetry

    Author : Marcus Larsson; Stefan Andersson-Engels; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Laser Doppler flowmetry (LDF) is based on the principle that a Doppler shift occurs when coherent light is scattered by a moving object, i.e. red blood cell (RBC). The magnitude of these frequency shifts affects the optical beating that occurs w hen shifted and non-shifted light is mixed. READ MORE

  5. 13. Fractionation of the stable silicon isotopes : analytical method developments and selected applications in geochemistry

    Author : Emma Engström; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : During the last few decades, variations in the 'natural' isotopic abundances of stable elements (termed 'fractionation') have received considerable interest from the scientific community. Though analytical methods and techniques for the measurement of isotopic abundances with adequate figures of merit have been available for light elements (e.g. READ MORE

  6. 14. Quantitative Laser Doppler Flowmetry

    Author : Ingemar Fredriksson; Tomas Strömberg; Marcus Larsson; Weindelt Stenbergen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical engineering; Medicinsk teknik;

    Abstract : Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering in the 1970s, and a rapid evolvement followed during the 1980s with fiber based systems and improved signal analysis. READ MORE
