  1. 1. The Non-Invasive Liver Biopsy : Determining Hepatic Function in Diffuse and Focal LiverDisease

    Författare :Mikael Forsgren; Peter Lundberg; Gunnar Cedersund; Bengt Norén; Olof Dahlqvist Leinhard; Steven Sourbron; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The liver is one of the largest organs within the human body and it handles many vital tasks such as nutrient processing, toxin removal, and synthesis of important proteins. The number of people suffering from chronic liver disease is on the rise, likely due to the present ‘western’ lifestyle. LÄS MER

  3. 2. Optical spectroscopy and fluorescence imaging for cancer diagnostics

    Författare :Pontus Svenmarker; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomedical optics; Diffuse-reflection spectroscopy; Upconverting nanoparticles; Inverse problem; Fluorescence; Tomography; Imaging; Scattering media; Photon migration; Fysicumarkivet A:2012:Svenmarker;

    Sammanfattning : This work presents optical methods for diagnosing cancer. A complementary method for diagnosing eye cancer was investigated using a technique developed within this work named transscleral optical spectroscopy (TOS). LÄS MER

  4. 3. Optical Monitoring of Cerebral Microcirculation

    Författare :Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

    Sammanfattning : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).

  5. 4. Model-based quantitative assessment of skin microcirculatory blood flow and oxygen saturation

    Författare :Hanna Jonasson; Tomas Strömberg; Bruce Tromberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The microcirculation, involving the smallest vessels in the body, is where the oxygen transport to all tissue occurs. Evaluating microcirculatory parameters is, therefore, important and involves the quantification of oxygen content of red blood cells (RBCs), the amount of RBCs and their speed. LÄS MER

  7. 5. The effect of extreme power densities applied to a planar magnetron

    Författare :Johan Böhlmark; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In plasma assisted thin film growth control over the energy and direction of the incoming species is desired. If the growth species are ionized this can be achieved by the use of a substrate bias. ions may be accelerated by an applied potential, whereas neutral particles may not. LÄS MER
