1. Creating Artificial Quantum Chiral States : Time Evolving Open Spin Chains
Kandidat-uppsats, Uppsala universitet/MaterialteoriSammanfattning : The discoveries in applications of chirality in various areas of science seem to never cease to emerge. Chirality, being the property that some objects are geometrically distinguishable from their mirror image, is a tiny difference of vast importance. LÄS MER
2. Improving proton therapy planning with photon-counting spectral computed tomography
Master-uppsats, KTH/FysikSammanfattning : Proton radiation therapy is an alternative to conventional photon radiation therapy, which accounts for the majority of radiation treatments today. The rationale for using protons in radiation therapy lies in their dose deposition properties; photons deposit a radiation dose inversely proportional to the energy, and therefore tissue depth, while protons exhibit a sharp Bragg peak when traversing matter.

3. 3d-utskrivet fantom för kontroll av linjär-acceleratorer
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik; Umeå universitet/Centrum för medicinsk teknik och fysik (CMTF)Sammanfattning : Cancer är en sjukdom som var tredje person får som diagnos under en livstid. Stor del av dessa cancerpatienter får behandling med hjälp av strålbehandling. Där strålbehandlingen kan ske med en linjäraccelerator. Linjäracceleratorn producerar elektron eller fotonstrålning i Mega Volt energiområde. LÄS MER
4. Respiratory Motion Correction in PET Imaging: Comparative Analysis of External Device and Data-driven Gating Approaches
Master-uppsats, KTH/FysikSammanfattning : Positron Emission Tomography (PET) is pivotal in medical imaging but is prone to artifactsfrom physiological movements, notably respiration. These motion artifacts both degradeimage quality and compromise precise attenuation correction. LÄS MER
5. Exploratory Analysis of Isoelectric Point Prediction with Simple Feature Encoding
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Proteomics is the large scale study of proteins in biological systems such as those found in human cells. The understanding of proteomes, i.e. the complete set of proteins expressed by an organism, has especially useful applications in the medical field such as genetic research and drug discovery. LÄS MER
