  3. 7. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Adam Hjalmarsson; Leon Ericsson; [2023]
    Keywords : 4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Abstract : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.

  4. 8. Pure Yang-Mills amplitudes in 5 Dimensions : A study of vector boson amplitudes at 4 and 5 points

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Athanasios Voutouras; [2023]
    Keywords : Yang-Mills; Scattering; Amplitudes; QFT;

    Abstract : In this text we explore the case of pure Yang-Mills amplitudes in 5 spacetime dimensions for vector particles. Extending current toolsets such as the Spinor-Helicity formalism in 5D would be beneficial to the study of the various cases of super Yang-Mills and supergravity. READ MORE

  5. 9. Inclusion of more sources in a commercial brachytherapy Monte Carlo

    University essay from

    Author : Philip Wiman; Emil Forsberg; Robin Vestling; [2023]
    Keywords : ;

    Abstract : Brachytherapy is a cancer treatment method where a solid radioactive source is placed inside the body in order to target cancer cells with a high dose of radiation while minimizing damage to surrounding healthy tissue. The most common method for treatment planning in brachytherapy is the TG43 formalism where the whole patient geometry is treated as water. READ MORE

  6. 10. Deep learning for temporal super-resolution of 4D Flow MRI

    University essay from KTH/Matematik (Avd.)
