1. 1. Radiotherapy treatment strategy for prostate cancer with lymph node involvement

   University essay from Umeå universitet/Institutionen för fysik

   Author : Amanda Östensson; [2023]
   Keywords : Radiotherapy; prostate cancer; lymph node; gold fiducial marker; multiple target;

   Abstract : 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.

3. 2. Development of a new SBRT dose planning strategy for thoracic tumours in RayStation

   University essay from Umeå universitet/Radiofysik

   Author : Olof Westman; [2023]
   Keywords : radiotherapy sbrt lung robust; radioterapi;

   Abstract : 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. READ MORE

4. 3. Multi-ion radiotherapy treatment planning

   University essay from Uppsala universitet/Högenergifysik

   Author : Gustav Lidberg; [2023]
   Keywords : multi-ion radiotherapy; heavy-ion radiotherapy; carbon-ion radiotherapy; treatment planning; LET optimization;

   Abstract : 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. READ MORE

5. 4. Optimization of Radiotherapy Treatment Plans Based on Monte Carlo Dose Computations

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Ludvig Håkansson; [2023]
   Keywords : Technology and Engineering;

   Abstract : 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. READ MORE

6. 5. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Thi Guldhill; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE
