1. Radiation therapy of upper gastrointestinal cancers with scanned proton beams : A treatment planning study
Sammanfattning : Proton beam therapy (PBT), using scanned beams, is an emerging modality used for the treatment of cancer. The clinical advantages of PBT, compared to commonly used photon beam therapy, have been demonstrated in different studies. LÄS MER
2. Development of a Whole Body Atlas for Radiation Therapy Planning and Treatment Optimization
Sammanfattning : The main objective of radiation therapy is to obtain the highest possible probability of tumor cure while minimizing adverse reactions in healthy tissues. A crucial step in the treatment process is to determine the location and extent of the primary tumor and its loco regional lymphatic spread in relation to adjacent radiosensitive anatomical structures and organs at risk.

3. Radiobiological investigations of proton and light ion therapy
Sammanfattning : During the last decade, the interest in proton and light ion beam therapy has increased considerably and several new centres are planned around the world. These particles have a large advantage due to their sharp physical dose distributions as compared to conventional radiotherapy beams. LÄS MER
4. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams
Sammanfattning : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. LÄS MER
5. Antenna Design, Radiobiological Modelling, and Non-invasive Monitoring for Microwave Hyperthermia
Sammanfattning : The death toll of cancers is on the rise worldwide and surviving patients suffer significant side effects from conventional therapies. To reduce the level of toxicity in patients treated with the conventional treatment modalities, hyperthermia (HT) has been investigated as an adjuvant modality and shown to be a potent tumor cell sensitizer for radio- and chemotherapy.
