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. New Efficient Detector for Radiation Therapy Imaging using Gas Electron Multipliers

   Author : Janina Östling; Mats Danielsson; Anders Brahme; Fabio Sauli; Stockholms universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Portal imaging; Gas Electron Multiplier; Gas detector; Medical engineering; Medicinsk teknik;

   Abstract : Currently film is being replaced by electronic detectors for portal imaging in radiation therapy. This development offers obvious advantages such as on-line quality assurance and digital images that can easily be accessed, processed and communicated. READ MORE

5. 3. High resolution laboratory x-ray tomography for biomedical research : From design to application

   Author : Till Dreier; Lund Medicinsk strålningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray; computed tomography; micro-CT; nano-CT; phase contrast; biomedical; super-resolution; material decomposition;

   Abstract : Laboratory x-ray micro- and nano-tomography are emerging techniques in biomedical research. Through the use of phase-contrast, sufficient contrast can be achieved in soft tissue to support medical studies. READ MORE

6. 4. X-ray and neutron μCT of biomedical samples: from image acquisition to quantification

   Author : Niccoló Peruzzi; Lund Medicinsk strålningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray imaging; neutron imaging; μCT; synchrotron radiation; x-ray phase-contrast; nanoholotomography; x-ray elemental mapping; biomedical applications; virtual histology; biodegradable implants; Mg-alloys; enteric nervous system; peripheral neuropathy; gastroenteric dysmotility; Fysicumarkivet A:2021:Peruzzi;

   Abstract : Even though the validity of x-ray computed tomography in the analysis of biomedical samples is nowadays undisputed, the more recent imaging techniques and more advanced instruments (such as synchrotrons) are still relatively unknown to many medical doctors that could benefit from them.The doctoral work presented in this thesis joins a collective effort from the imaging community to demonstrate potential applications of advanced x-ray and neutron imaging methods to preclinical medical research, with the hope of contributing to reach a “critical mass” in the medical community and in the public opinion as well.

7. 5. Improved dose response modeling for normal tissue damage and therapy optimization

   Author : Magdalena Adamus-Górka; Bengt K. Lind; Anders Brahme; Panayiotis Mavroidis; Randall K. Ten Haken; Stockholms universitet; []
   Keywords : Normal tissue complications; radiobiological models; dose-response; volume effect; spinal cord; effective FSU size; medicinsk strålningsfysik; Medical Radiation Physics;

   Abstract : The present thesis is focused on the development and application of dose response models for radiation therapy. Radiobiological models of tissue response to radiation are an integral part of the radiotherapeutic process and a powerful tool to optimize tumor control and minimize damage to healthy tissues for use in clinical trials.
