  1. 6. ATLAS DATABASES OF HUMAN BRAIN ANATOMY: QUALITATIVE AND QUANTITATIVE COMPARISON

    Master-uppsats,

    Författare :Amanda Philipsson Franzén; [2021-01-11]
    Nyckelord :Medical physics; Brain atlas concordance problem; Quantitative comparison; Qualitative comparison; Hammersmith; 2012 MICCAI Multi-Atlas Labelling Challenge Data;

    Sammanfattning : The purpose of this study was to quantitatively and qualitatively compare the two brain atlases databases, Hammersmith and 2012 MICCAI Multi-Atlas Labelling Challenge data, by developing a quantitative method. Theory Anatomical atlases of the human brain provide reference information about its structure. LÄS MER

  3. 7. Prioritization of Informative Regions in PET Scans for Classification of Alzheimer's Disease

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Fredrik Mårtensson; Erik Westberg; [2021]
    Nyckelord :;

    Sammanfattning : Alzheimer’s Disease (AD) is a widespread neurodegenerative disease. The disease causes brain atrophy, resulting in memory loss, decreased cognitive ability, and eventually death. There is currently no cure for the disease, but treatment may delay the onset. Therefore, it is crucial to detect the disease at an early stage. LÄS MER

  4. 8. Überatlas: Robust speed-up of feature-based registration and multi-atlas based segmentation

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Jennifer Alvén; [2015]
    Nyckelord :computer vision; medical image analysis; feature-based registration; segmentation of pericardium; segmentation of brain; multi-atlas based segmentation; Mathematics and Statistics;

    Sammanfattning : Registration is a key component in multi-atlas approaches to medical image segmentation. Current state-of-the-art uses intensity-based registration methods, but such methods tend to be slow and sensitive to large amount of noise and anatomical abnormalities present in medical images.

  5. 9. Brain MRI segmentation for the longitudinal follow-up of regional atrophy in Alzheimer’s Disease

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Clemence Petit; [2014]
    Nyckelord :Segmentation; MRI; Brain; Alzheimer s Disease; Tissue classification; Graph-cuts optimization;

    Sammanfattning : Brain atrophy measurement is increasingly important in studies of neurodegenerative diseases such as Alzheimer’s disease. From this perspective, a regional segmentation framework for magnetic resonance images has recently been developed by the team that I joined for my master thesis. It combines an atlas fusion and a tissue classification. LÄS MER
