6. Advancing Upconversion Emissions for Biomedical Imaging
Sammanfattning : During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical applications.

7. Aspects of Optical Broad Band Spectroscopy and Information Extraction - Applications in Medicine and Ecology
Sammanfattning : The present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. LÄS MER
8. Optical spectroscopy in biomedicine - detection of embedded inclusions and in vivo pharmacokinetics
Sammanfattning : The main theme of this thesis is the use of fluorescence spectroscopy in biomedicine. The work presented in the thesis can be divided into three areas of applications. The first area involves the use of fluorescence to find the location of a deeply situated fluorophore within turbid media. LÄS MER
9. Non-Euclidean structures in PCA-based descriptions of multispectral databases
Sammanfattning : Traditional color science is based on human color vision. For many applications (for example remote sensing, medical imaging, industrial inspection) where spectral properties of the radiation are of interest, human color vision based systems are too restrictive. Therefore multispectral approaches are becoming more and more popular. LÄS MER
10. Spectroscopic Measurements and Fluorescence Imaging for Treatment and Diagnosis of Skin Cancer
Sammanfattning : This thesis deals with the use of light for treatment and diagnosis of skin cancer. The occurrence of skin cancer is increasing worldwide, among the most common types being basal cell carcinoma, squamous cell carcinoma and actinic keratosis, a skin cancer precursor. LÄS MER
