  1. 1. Enabling Hybrid Real Time and Retrospectively Gated Imaging in a Numerical Phantom

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sara Mineur; [2023]
    Nyckelord :Cardiovascular Magnetic resonance Imaging CMR ; Sector Wise Golden-Angle SWIG ;

    Sammanfattning : Sector-Wise Golden Angle (SWIG) is a novel approach that was developed to address the limitations associated with Golden Angle radial imaging, commonly used for high temporal resolution flow measurements. Golden angle radial imaging is a time-efficient method that effectively reduces motion sensitivity. LÄS MER

  3. 2. Deep learning for temporal super-resolution of 4D Flow MRI

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Pia Callmer; [2023]
    Nyckelord :Temporal super-resolution; 4D Flow MRI; CNN; Artificial Intelligence; MRI; 4D flow; Temporal superupplösning; 4D flöde MRI; CNN; artificiell intelligens; MRI; 4D-flöde;

    Sammanfattning : The accurate assessment of hemodynamics and its parameters play an important role when diagnosing cardiovascular diseases. In this context, 4D Flow Magnetic Resonance Imaging (4D Flow MRI) is a non-invasive measurement technique that facilitates hemodynamic parameter assessment as well as quantitative and qualitative analysis of three-directional flow over time.

  4. 3. Preparation and Characterization of Tb-Co Magnetic Films

    L2-uppsats, Uppsala universitet/Materialfysik

    Författare :Roméo Beignon; [2022]
    Nyckelord :Thin Film; TbCo; Out-of-Plane Anisotropy; Magnetic Domains;

    Sammanfattning : Thin films of terbium-cobalt alloy have been deposited by magnetron sputtering. They exhibit an out-of-plane magnetic anisotropy that may result in elongated domains. The effect of thicknesses and compositions on the domain structure has been studied systematically. LÄS MER

  5. 4. Assignment of heteronuclear methyl-NMR spectrum of the 44 kDa protein MALT1 Casp-IgL3

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Maria Levkovets; [2022]
    Nyckelord :MALT1; NMR; methyl-NMR; protein NMR; Physics and Astronomy;

    Sammanfattning : Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) plays an important role in the immune pathway that controls the activation and proliferation of B and T cells. Dysregularization of this pathway leads to the development of highly aggressive lymphomas. LÄS MER

  7. 5. 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
