2. Gas in Scattering Media Absorption Spectroscopy in Large Geometries: Towards Monitoring Oxygen in Adult Lungs
Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenSammanfattning : GAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. LÄS MER
3. Bearbetning av digitala röntgenbilder : en enkätstudie i hur olika bearbetningar påverkar bedömningen av knäledsröntgen på hund och katt
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical SciencesSammanfattning : Röntgen används dagligen i den veterinärmedicinska kliniken och är ett mycket användbart diagnostiskt verktyg. I dagsläget existerar röntgensystem där användaren har stora möjligheter att bearbeta den digitala röntgenbilden på olika sätt och på det viset skapa röntgenbilder med olika utseenden. LÄS MER
4. Characterization of Radiomics Features Extracted from Images Generated by the 0.35 T Scanner of an Integrated MRI-Linac
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Purpose: In an era of personalized oncology where the aim is to give every patient the right treatment at the right time an area of promising research is emerging called radiomics, or quantitative image analysis. The main underlying hypothesis is that pathophysiological information can be found in image texture not visible to the bare eye that can improve diagnosis, treatment adaption or be linked to a certain clinical outcome.

5. Movement tracking of the carotid artery with 4D ultrasound imaging
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : The leading cause of death in the world is cardiovascular diseases. Scientific discoveries have been made that correlate the movement of the arterial walls and blood flow patterns with cardiovascular diseases. These movements have been studied with ultrasound 2D imaging. LÄS MER
