6. Radiotherapy treatment strategy for prostate cancer with lymph node involvement
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Radiotherapy is a common and useful method for treating prostate cancer, often using gold fiducial markers in the prostate as guidance. However, when there is a high risk of lymph node involvement, the independent motion of volumes causes complications in patient positioning since there is a choice between position against the gold fiducial markers or the bone anatomy.

7. Development of a new SBRT dose planning strategy for thoracic tumours in RayStation
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/RadiofysikSammanfattning : Umeå University Hospital has acquired a new treatment planning system, RayStation, for radiotherapy. It has a different set of dose calculation algorithms that require new planning strategies for stereotactic lung cancer treatments. LÄS MER
8. Multi-ion radiotherapy treatment planning
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/HögenergifysikSammanfattning : Multi-ion radiotherapy has been suggested as a new way to treat cancer, combining the radiological advantages of lighter and heavier ions in a single treatment to improve plan robustness and increase LETd in the target. To succeed, multi-ion radiotherapy requires a treatment planning system capable of computing dose for and optimising multi-ion treatment plans. LÄS MER
9. Optimization of Radiotherapy Treatment Plans Based on Monte Carlo Dose Computations
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : Treatment planning plays a vital role in providing good treatment to cancer patients. In order to reach an adequate treatment plan, the algorithm used for simulating the dose in the patient must model the reality well. LÄS MER
10. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. LÄS MER
