1. Texture Analysis and Ultra high-frequency ultrasound in use for diagnosing Hirschsprung's disease
Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : An investigation into the use of statistical texture analysis in combination with ultra high-frequency ultrasound for diagnosing Hirschsprung’s disease (HD); An illness that manifests itself through the absence of ganglia cells in lower parts of the intestine. Current diagnostic techniques carry a higher risk of long-term consequences in newborns and children which enables a new avenue of research into new methods. LÄS MER
2. Sustainable reduction of asbestos sample losses using Radio Frequency Identification and the 5S method
Master-uppsats, KTH/KemiteknikSammanfattning : This study is a research around an issue encountered by MyEasyLab, a laboratory involved in asbestos testing for the French market. They are facing a problem of sample losses, which is hardly acceptable, especially when growing on a highly competitive and price driven market. LÄS MER
3. 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.

5. Decrease radiated emission from high frequency links
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : There is a need for increasing speed on external links and harmonics are often seen and are a challenge to master. Especially for products within the space industry where the requirements are narrower due to the harsh environment it needs to withstand. LÄS MER
