  1. 1. Spectral Image Processing with Applications in Biotechnology and Pathology

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Milan Gavrilovic; Uppsala universitet.; Uppsala universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; color theory; light microscopy; spectral imaging; image analysis; digital image processing; mathematical modeling; estimation; noise models; spectral decomposition; color decomposition; colocalization; cross-talk; autofluorescence; tissue separation; prostate cancer; biomedical applications; molecular biotechnology; histopathology; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Color theory was first formalized in the seventeenth century by Isaac Newton just a couple of decades after the first microscope was built. But it was not until the twentieth century that technological advances led to the integration of color theory, optical spectroscopy and light microscopy through spectral image processing. READ MORE

  2. 2. Characterization of [18F]flutemetamol binding properties A β-amyloid PET imaging ligand

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kerstin Heurling; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography PET ; molecular imaging; amyloid; tracer validation; Radiology; Radiologi;

    Abstract : The criteria for diagnosing Alzheimer’s disease (AD) have recently been revised to include the use of biomarkers for the in vivo presence of β-amyloid, one of the neuropathological hallmarks of AD. Examples of such biomarkers are positron emission tomography (PET) β-amyloid specific ligands, including [18F]flutemetamol. READ MORE

  3. 3. Model-based Approaches to Diffuse Optical Imaging and Dosimetry

    University dissertation from Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Author : Johan Axelsson; Lund University.; Lunds universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodynamic therapy; diffuse light propagation; fluorescence; imaging; dosimetry; inverse problem;

    Abstract : The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. READ MORE

  4. 4. Colorimetric and Multispectral Image Acquisition

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Daniel Nyström; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Spectral reconstruction; Device characterization; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys;

    Abstract : The trichromatic principle of representing color has for a long time been dominating in color imaging. The reason is the trichromatic nature of human color vision, but as the characteristics of typical color imaging devices are different from those of human eyes, there is a need to go beyond the trichromatic approach.

    Abstract : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.
