2. 1. Absorbed dose and biological effect in light ion therapy

   Author : Malin Hollmark; Irena Gudowska; Oliver Jäkel; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Light ion therapy; absorbed dose calculation; analytical pencil beam model; Monte Carlo; radiobiological modeling; Radiological physics; Radiofysik; medicinsk strålningsfysik; Medical Radiation Physics;

   Abstract : Radiation therapy with light ions improves treatment outcome for a number of tumor types. The advantageous dose distributions of light ion beams en-able exceptional target conformity, which assures high dose delivery to the tumor while minimizing the dose to surrounding normal tissues.

4. 2. 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

5. 3. Secondary absorbed dose distributions and radiation quality in light ion therapy

   Author : Martha Hultqvist; Irena Gudowska; Tatsuhiko Sato; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; secondary doses; light ion therapy; radiation quality; Monte Carlo simulation; Medical Radiation Physics; medicinsk strålningsfysik;

   Abstract : Radiotherapy with light ions offers the possibility of achieving a dose distribution which is highly conformed to the target volume while sparing normal tissues. For ions heavier than protons, an additional advantage is the increased Relative Biological Effectiveness (RBE) as compared to conventional photon and electron beams. READ MORE

6. 4. Development of analytical transport methods for biologically optimized light ion therapy

   Author : Johanna Kempe; Anders Brahme; Irena Gudowska; Naruhiri Matsufuji; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; radiation quality; energy-range relations; light ion transport; pencil beam; Monte Carlo; Physics; Fysik; medicinsk strålningsfysik; Medical Radiation Physics;

   Abstract : A general objective in the treatment of cancer is to eradicate the tumour cells without inducing severe complications in healthy normal tissue. The use of light ions for radiation therapy increases the possibility to deliver tumour suicidal doses with very low probability of normal tissue injury, not least in cases where the target is unresectable, radioresistant and located to near organs at risk.

7. 5. Development of Novel Hydroporphyrins for Light Harvesting and Sensitising NIR Lanthanide Luminescence

   Author : Ruisheng Xiong; Eszter Borbas; Christian Brückner; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; chlorin; hydroporphyrin; chlorophyll analogues; light harvesting; lanthanide luminescence; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

   Abstract : Chlorins, as the core structures of chlorophylls, have been extensively studied for harvesting solar energy, fluorescent imaging and photodynamic therapy against cancer. This thesis is concerned with design and synthesis of novel chlorins as antennae for harvesting light and sensitising near infrared lanthanide luminescence. READ MORE
