  1. 1. Cybersickness in a Virtual and Mixed Reality Flight Simulator With a Video See-Through Head-Mounted Display

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Christian K. K. Lindberg; [2023]
    Nyckelord :cybersickness; virtual reality; mixed reality; flight simulator; military; cybersjuka; virtuell verklighet; blandad verklighet; flygsimulator; militär;

    Sammanfattning : The Swedish Air Force Combat Simulation Centre (FLSC) is investigating how immersive technologies can be used with flight simulators. Cybersickness is sickness-like effects experienced when immersed in virtual environments using head-mounted displays. LÄS MER

  3. 2. Quantitative susceptibility mapping of the knee: A comparison of approaches for addressing fatty tissue

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Cornelia Säll; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. LÄS MER

  4. 3. Utvärdering av två olika diffusionsviktade sekvenser vid MR-prostata.

    Magister-uppsats, Umeå universitet/Institutionen för omvårdnad

    Författare :Jimmy Kyrk; [2022]
    Nyckelord :MRI; prostate; artifacts; comparative; diffusion; MRT; prostata; artefakter; jämförande; diffusion;

    Sammanfattning : Bakgrund: Protokollet som används för att underundersöka MR-prostata innehåller en uppsättning förutbestämda sekvenser enligt PI-RADS riktlinjer. Diffusionsviktade bilder används för att utröna om vattenmolekyler kan röra sig fritt eller inte. Begränsad rörlighet kan tyda på patologi. LÄS MER

  5. 4. 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

  7. 5. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Mustafa Kadhim; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: The MP2RAGE technique has become popular for structural MRI at ultra-high fields. The core idea behind MP2RAGE is to reduce the influence of flip angle inhomogeneity (B +), proton density and T2* by calculating the regularized signed ratio of two complex MP-RAGE images acquired at different inversion times (TI) within the cycle.
