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)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
2. Quantitative susceptibility mapping of the knee: A comparison of approaches for addressing fatty tissue
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : 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
3. Utvärdering av två olika diffusionsviktade sekvenser vid MR-prostata.
Magister-uppsats, Umeå universitet/Institutionen för omvårdnadSammanfattning : 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
4. Data Augmentation to Improve Cross-Domain Generalization in Deep Learning MRI Segmentation
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : 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
5. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : 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.
