1. 1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

   University essay from Lunds universitet/Fysiska institutionen

   Author : Klara Stefansson; [2024]
   Keywords : Technology and Engineering;

   Abstract : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. READ MORE

3. 2. Apoptosis induction in breast cancer cells after radiotherapy and potential radiosensitizers

   University essay from

   Author : Klara Simonsson; [2023-06-27]
   Keywords : Medical physics; Breast cancer cells; radiotherapy; systemic therapy; combination therapy; apoptosis; BH3 profiling; flow cytometry;

   Abstract : Background. Today breast cancer is the foremost cancer death type amongst women around the world. At present some of the toughest challenges in the clinic is recurrent, radioresistant breast cancer, and metastatic breast cancer where low cure rates are observed after surgery and radiotherapy.

4. 3. 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.

5. 4. 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

6. 5. 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
