2. 1. Radiobiological investigations of proton and light ion therapy

   Author : Nina Tilly; Michael Scholz; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiobiology; Monte Carlo method; Radiotherapy; high-energy instrumentation; Protons; Light ions; RBE; LET; Radiobiological models; Radiobiologi; medicinsk strålningsfysik; Medical Radiation Physics;

   Abstract : 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. READ MORE

4. 2. Mixed Beam Dosimetry - From Reactor Core to BNCT Patient

   Author : Per Munck af Rosenschöld; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BNCT; dosimetry; radiotherapy; mixed beam; quality assurance; in vivo dosimetry; Monte Carlo; ionization chamber; foil activation; MCNP; beam quality correction factor; photon transmission.; Nukleärmedicin; radiobiology; Nuclear medicine; radiobiologi; Radiofarmaceutisk teknik; Radiopharmaceutical technology;

   Abstract : Accurate radiation dosimetry is of paramount importance in order to ensure safe delivery of radiotherapy, and for the possibility of meaningful evaluation of clinical trials, as the radiation absorbed dose is correlated to tissue response. The aim of the studies described in this thesis was to investigate and devise novel approaches to mixed beam dosimetry in boron neutron capture therapy (BNCT). READ MORE

5. 3. Improving the therapeutic ratio of stereotactic radiosurgery and radiotherapy

   Author : Bahram Andisheh; Bengt Lind; John Hopewell; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimization; stereotactic radiosurgery; stereotactic radiotherapy; radiobiology; modeling; Medical Radiation Physics; medicinsk strålningsfysik;

   Abstract : New methods of high dose delivery, such as intensity modulated radiation therapy (IMRT), stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS), hadron therapy, tomotherapy, etc., all make use of a few large fractions. READ MORE

6. 4. Long-term outcome research on PDR brachytherapy with focus on breast, base of tongue and lip cancer

   Author : Bengt Johansson; Jan Persliden; Jan Nyman; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDR; brachytherapy; outcome; partial breast irradiation; base of tongue cancer; lip cancer; quality of life; dosimetry.; Oncology; Onkologi; Surgery; Kirurgi; Onkologi; Oncology; Surgery; Kirurgi;

   Abstract : Brachytherapy (BT) with continuous low dose rate (LDR) has been used for 100 years and is considered as the radiotherapy method able to deliver a dose in the shortest time with high efficacy and low risk of side effects. The drawbacks are need for patient isolation and radiation exposure of the staff during the treatment. READ MORE

7. 5. Tailoring Radionuclide Therapy of Neuroendocrine Tumors - Bridging the Gaps

   Author : Anna Sundlöv; Tumörmikromiljö; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 177Lu-DOTATATE; PRRT; somatostatin analogs; pituitary function; renal function; dosimetry; 68Ga-DOTATATE; individualized treatment; neuroendocrine tumors;

   Abstract : Background and Aims: Radionuclide therapy is systemic, targeted radiotherapy. As such, we can apply the basic principles of radiobiology used in everyday practice in radiation oncology, as a means of tailoring the treatment to each patient and optimizing the balance between efficacy and toxicity.
