      Master of science - ms health/medical physics 8.06

      MSc thesis with title "Development of medical image segmentation algorithms for focal liver lesion extraction in MR images". The technique of segmentation was studied that plays a dominant role in the field of medical image analysis and processing. The medical images that were processed came from an MRI scan and depict liver lesions (benign and malignant). The anatomy and physiology of the liver in both a healthy and pathological environment are described in detail. The segmentation algorithms… Show more MSc thesis with title "Development of medical image segmentation algorithms for focal liver lesion extraction in MR images". The technique of segmentation was studied that plays a dominant role in the field of medical image analysis and processing. The medical images that were processed came from an MRI scan and depict liver lesions (benign and malignant). The anatomy and physiology of the liver in both a healthy and pathological environment are described in detail. The segmentation algorithms of K-Means, Fuzzy C-Means, Markov Random Fields and were studied and the experimental results are presented with the conclusion and concerns. The algorithms were first tested on phantom images and then applied to medical images by Μagnetic Resonance Imaging. Finally, the Jaccard Index, which is a criterion for comparing algorithms, was calculated. The algorithms were developed, modified and executed in MATLAB programming environment. Show less

      Undergraduate Research Thesis: "The photophysical properties of three organic chromophores were investigated. Specifically the dyes Rhodamine 6G, Fluorescein (free acid) and Rhodamine B in aqueous solution were investigated. Also, we studied energy transfer phenomena in pairs of Fluorescein-Rhodamine 6G and Fluorescein-Rhodamine B in various concentrations. The experimental study was performed with steady state spectroscopy, as well as with time resolved spectroscopy via the technique of Time… Show more Undergraduate Research Thesis: "The photophysical properties of three organic chromophores were investigated.
