1. The Non-Invasive Liver Biopsy : Determining Hepatic Function in Diffuse and Focal LiverDisease
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
2. Optical spectroscopy and fluorescence imaging for cancer diagnostics
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
3. Optical Monitoring of Cerebral Microcirculation
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).

4. Model-based quantitative assessment of skin microcirculatory blood flow and oxygen saturation
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
5. The effect of extreme power densities applied to a planar magnetron
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
