1. Laser doppler tissue flowmetry : fiberoptic methods in microvascular research
Sammanfattning : Laser Doppler flowmetry (LDF) constitutes a method for measuring the flux of blood cells in the microcirculatory bed. Photons are scattered in the moving blood cells, where they undergo a frequency shift according to the Doppler principle. LÄS MER
2. Multispectral imaging of hemoglobin oxygen saturation in skin microcirculation
Sammanfattning : The ability to measure microcirculatory parameters such as hemoglobin oxygen saturation is important since it mirrors the microcirculatory state of the body. The microcirculation delivers oxygen and nutrients to the cells of the body and, if impaired, may be a sign of circulatory failure. LÄS MER
3. Fluorescence Spectroscopy for Quantitative Demarcation of Glioblastoma Using 5-Aminolevulinic Acid
Sammanfattning : Total resection of glioblastoma, the highly malignant brain tumor, is difficult to accomplish due to its diffuse growth and similarity to the surrounding brain tissue. A total resection is proven to increase patient survival. LÄS MER
4. In Vivo Diffuse Reflectance Spectroscopy of Human Tissue : From Point Measurements to Imaging
Sammanfattning : This thesis presents the non-invasive use of diffuse reflectance spectroscopy (DRS) to provide information about the biochemical composition of living tissue. During DRS measurements, the incident, visible light is partially absorbed by chromophores but also scattered in the tissue before being remitted. LÄS MER
5. Action Potential Generator and Electrode Testing
Sammanfattning : Design, validation and application of a test platform for electrode characterization and comparison is a problem today. Development of target specific electrodes is increasing, for example surface cloth electrodes, non-contact electrodes, and deep brain stimulation electrodes. LÄS MER
