    Sammanfattning : Decision‐makers in organisations and businesses make numerous decisions every day, and these decisions are expected to be based on facts and carried out in a rational manner. However, most decisions are not based on precise information or careful analysis due to several reasons. People are, e.g. LÄS MER

  3. 12. Applications of statistical methods in quantitative magnetic resonance imaging

    Författare :Patrik Brynolfsson; Anders Garpebring; Tufve Nyholm; Eirik Malinen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiation physics;

    Sammanfattning : Magnetic resonance imaging, MRI, offers a vast range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow ups, or assessment of treatment response. LÄS MER

  4. 13. Quantitative magnetic resonance in diffuse liver and neurological disease

    Författare :Olof Dahlqvist Leinhard; Linköpings universitet; []
    Nyckelord :Mapping--methods; Choline--analysis; Liver diseases--diagnosis; Magnetic resonance imaging--methods; Magnetic resonance spectroscopy--methods; Multiple sclerosis--diagnosis; Multiple sclerosis--metabolism; Nerve fibers; myelinated--metabolism; MEDICINE; MEDICIN;

    Sammanfattning : Magnetic resonance (MR) has become one of the most important diagnostic tools in modern medicine. It provides superior soft tissue contrast compared to other imaging modalities, it is extremely flexible as it can be used to image all parts of the body, and it is considered to be safe for patients.

  5. 14. Advances in quantitative emission tomography : development and analysis of methods for validation and correction

    Författare :Cathrine Jonsson; Magnus Dahlbom; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SPECT; Quantification; rCBF; Scatter correction; Phantoms; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : The nuclear medicine imaging techniques SPECT and PET are sensitive tools in mapping various physiological and biochemical processes in vivo. This work was devoted to investigations of methodological and physical properties of the SPECT technique as well as developing methods for validation and correction. LÄS MER

  7. 15. Quantitative Assessment of Intelligent Transport Systems for Road Freight Transport

    Författare :Gideon Mbiydzenyuy; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transport telematic services; Assessment; Freight transport; Quantitative; Modeling; Decision support systems;

    Sammanfattning : In this thesis, methods for using computer-based models as support tools for assessing Transport Telematic Services (TTSs) are studied. Such assessments provide one way to understand how TTSs can address problems caused by transportation, such as accidents, emissions, and energy consumption. LÄS MER
