  1. 1. Data Augmentation to Improve Cross-Domain Generalization in Deep Learning MRI Segmentation

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Rasmus Helander; [2021]
    Nyckelord :deep learning; medical imaging; mri; segmentation; data augmentation; cyclegan; noisy labels; Mathematics and Statistics;

    Sammanfattning : Semantic segmentation of medical images is an important task with many applications. However, manually delineating 3D images is time-consuming and the demand for automation is high. For many image segmentation tasks, deep learning has provided state-of-the-art results. LÄS MER

  3. 2. Optimization of Simultaneous Multi Slice EPI for clinical fMRI

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Andrea Fingerhut; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Functional MRI is a method used to map brain functionality, where the blood oxygen level (BOLD) imaging method is frequently used. Stimulation of neurons leads to an increase in energy and oxygen consumption and signal can be detected since oxygen changes the magnetic properties of the blood. LÄS MER

  4. 3. Automatic Localization of Bounding Boxes forSubcortical Structures in MR Images UsingRegression Forests

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Lars Lowe Sjösund; [2013]
    Nyckelord :;

    Sammanfattning : Manual delineation of organs at risk in MR images is a very time consuming task for physicians, and to be able to automate the process is therefore highly desirable. This thesis project aims to explore the possibility of using regression forests to nd bounding boxes for general subcortical structures. LÄS MER
