  1. 1. Investigating the Distance to Display Holographic Shelf Information in Retailing

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Mattias Johansson; [2018]
    Nyckelord :;

    Sammanfattning : This paper explores how mixed reality (MR) can be implemented in a brick-and-mortar store. More specifically, it explores at what distances information about shelves should be shown to give users the best possible experience. LÄS MER

  3. 3. Developing a Semi-Automatised Tool for Grading Brain Tumours with Susceptibility-Weighted MRI

    Master-uppsats, Umeå universitet/Umeå universitet/Umeå universitet/Institutionen för fysikRadiofysikCentrum för medicinsk teknik och fysik (CMTF)

    Författare :Maria Duvaldt; [2015]
    Nyckelord :Glioma grading; astrocytoma; suceptibility-weighted imaging; SWI; local image variance; intratumoural susceptibility signal; ITSS;

    Sammanfattning : Gliomas are a common type of brain tumour and for the treatment of a patient it is important to determine the tumour’s grade of malignancy. This is done today by a biopsy, a histopathological analysis of the tumourous tissue, that is classified by the World Health Organization on a malignancy scale from I to IV. LÄS MER

  4. 4. Variations in the target definition on CT and MR based treatment plans for radiotherapy

    Master-uppsats, Umeå universitet/Centrum för medicinsk teknik och fysik (CMTF)Umeå universitet/Institutionen för fysik

    Författare :Sara Svensson; [2014]
    Nyckelord :Magnetic resonance; computed tomography; radiotherapy; target definition; margins; prostate cancer; Magnetisk resonanstomografi; datortomografi; strålterapi; targetritning; prostatacancer;

    Sammanfattning : The introduction of Magnetic Resonance (MR) Imaging in treatment planning for radiotherapy of prostate cancer give rise to new challenges in defining the treatment volume, or the target. Imaging with MR have several advantages, especially better soft-tissue contrast, compared with the standard image modality, Computed Tomography (CT). LÄS MER

  5. 5. Diffuse reflectance spectroscopy as a tool to evaluate liver tissue

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Atomfysik

    Författare :Therese Alburg; David Kraus; [2014]
    Nyckelord :diffuse reflectance spectroscopy; drs; biophotonics; medical optics; diffusion; tissue evaluation; Technology and Engineering;

    Sammanfattning : The shape of a diffuse reflectance spectra can provide knowledge about tissue composition. By analysing this spectra one can, with the right evaluation methods, find out information about the tissue. LÄS MER
