    Sammanfattning : Vertebrate eyes share a common ancestry as well as the basic design with a pupil, a retina and a lens. The lens is essential for perceiving the details in the world around us and ensures that a sharp image of the surroundings is focused onto the photoreceptors in the retina. LÄS MER

  2. 2. Studies on Polarised Light Spectroscopy

    Författare :Max Bergkvist; Simon Farnebo; Erik Tesselaar; Folke Sjöberg; Johan Thorfinn; Knut Kvernebo; Linköpings universitet; []

    Sammanfattning : This thesis project focuses on measurements of dermal microcirculation during vascular provocations with polarised light spectroscopy. This is done with a non-invasive method commercially available as Tissue viability imaging (TiVi) which measures concentration and oxygenation of red blood cells in the papillary dermis. LÄS MER

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

    Författare :Karin Wårdell; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : 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. LÄS MER
