11. Verification of Dose Calculation Algorithms in Treatment Planning Systems for External Radiation Therapy: A Monte Carlo Approach
Abstract : This thesis presents a new verification concept, the virtual accelerator, for dose calculation algorithms used in treatment planning systems (TPSs) for external beam radiotherapy. The algorithm input data required to implement a treatment unit in the TPS are generated by Monte Carlo simulations as are the beam reference data needed for the subsequent evaluation of the dose calculation algorithm.

12. Methodological improvements in quantitative MRI : Perfusion estimation and partial volume considerations
Abstract : The magnetic resonance imaging (MRI) scanner is a remarkable medical imaging device, capable of producing detailed images of the inside of the body. In addition to imaging internal tissue structures, the scanner can also be used to measure various properties of the tissue. READ MORE

13. Radionuclide Production with PET Cyclotrons, Applications and Preclinical Experiments
Abstract : Nuclear medicine is based on the radiotracer principle of George de Hevesy and the magic bullet concept by Ehrlich and focuses on the diagnosis, the treatment of diseases and the investigation of normal states within the human body using radiopharmaceuticals. A radiopharmaceutical is an atom or a chemical compound in which one or several atoms are replaced with a radionuclide. READ MORE

14. Preclinical Molecular Imaging using Multi-Isotope Digital Autoradiography - Techniques and Applications
Abstract : Molecular imaging, both in vivo and ex vivo, is playing an increasingly important role in preclinical medical research. When using radionuclide-labeled tracers, e.g. in the development of radiopharmaceuticals for diagnostic imaging or for radionuclide therapy, quantitative in vivo imaging can be performed using emission tomography.

15. Radiotherapy in a FLASH : Towards clinical translation of ultra-high dose rate electron therapy
Abstract : FLASH radiotherapy (FLASH-RT) is a promising new approach to radiotherapy that has the potential to transform the field. By administering radiation at ultra-high dose rates (UHDR) on a millisecond timescale, FLASH-RT may increase normal tissue tolerance compared to conventional radiotherapy while maintaining the anti-tumoral effect.
