Acknowledgements
Looking back at the last couple of years, this work certainly would not have been possible without the help of many people.
At first, I would like to express my sincere gratitude to Franz Pfeiffer. Your lecture on Biomedical Physics initially sparked my interest in X-ray imaging during my master’s studies, and I am very thankful for providing me with the opportunity, guidance and also freedom to explore this field in your group. It has been a great honour working for you during the last couple of years, in which I have learned a lot from you. Although your schedule is of course very packed, you would always find the time for a meeting when needed.
Thank you Martin Bech and Irene Zanette for introducing me to the life at a synchrotron.
I enjoyed the beamtimes we spent together and benefited a great deal from your experi-ence. Furthermore, thank you Martin for providing me with additional insights during the many discussions we had in the past years and co-supervising this thesis.
I was first introduced to laboratory X-ray imaging by Elena Eggl, Guillaume Potdevin and Andreas Malecki. Thank you for providing me with the foundations that I could build on.
It was a pleasure sharing the experimental grating setup and office island with Friedrich Prade. Furthermore, I want to thank Christoph Jud for his valuable help, especially in creating the first user-friendly implementation of our XTT algorithms. I am grateful to Yash Sharma for our countless discussions on dark-field imaging - although perhaps we should not start them on Friday afternoons in our next lives. Your working morales were truly inspiring and supportive.
Thank you to Tobias Lasser and Matthias Wieczorek of the CAMP chair at TUM In-formatics for our very close collaboration. Every other week I was looking forward to discussing new developments of the AXDT/XTT reconstruction during our bi-weekly meetings. Being surrounded by physicists most of the time, your non-physicist view on the topic was always very refreshing to see.
Many thanks to Kaye Morgan, who had to experience the drawbacks of being a na-tive English speaker, but never got tired of answering my questions on English writing.
Thank you Julia Herzen maintaining excellent connections to other chairs and obtaining many different types of samples.
The productive working environment at the Chair of Biomedical Physics can not be taken for granted. Therefore I would like to thank especially Nelly de Leiris, Brunhilde Vogt and Klaus Achterhold, who were always there throughout the years to help with administrative questions. Additionally, the efforts of the E17 IT-department to provide a working IT-infrastructure are greatly appreciated. In particular, thank you Martin Dierolf for resolving my several IT issues in record time. The projector framework developed and maintained by Andreas Fehringer was immensely helpful for this work, thank you for the effort you put into this project. Thank you also to all my other colleagues at the E17 chair for creating an enjoyable atmosphere during the last couple of years. Many of the people I have shared my office with also helped proofread this thesis.
Our laboratory equipment heavily depends on the excellent gratings and support pro-vided by Joachim Schulz from microworks GmbH, Dr. J¨urgen Mohr and their colleagues from the Institute of Microstructure Technology at the Karlsruhe Institute of Technology, for which I am very grateful. Thank you also to Andre Yaroshenko for assisting me with the implementation of the low-sensitivity setup.
Thank you Dr. Marianne Liebi and Dr. Manuel Guizar-Sicairos for providing us with excellent support at the cSAXS beamline during our measurements.
As the focus of this chair is on developing imaging methods, we naturally need objects to take images from. Hence, I am thankful to the many collaborations that provided us with samples and feedback on our results. In particular, thank you Dr. Paul Zaslansky (Charit´e) for the tooth sample for the SAXS experiment and Dr. Sylvain Deville (CNRS) for the freeze cast sample. Furthermore, thank you to Andreas Bachmann (iwb - TUM Mechanical Engineering), and Prof. Johann Kastner (FH Ober¨ostereich) and his group for providing interesting material science samples, even though no results of them were shown in this thesis. Equally, thanks to Dr. Jan Krischke and Dr. Thomas Baum of the Klinikum Rechts der Isar for the long collaboration on imaging the microstructure in bone.
In this day and age I feel obliged to thank the internet, especially everyone that pro-vides openly accessible services; and Google to find them. The possibility to find existing solutions to every-day problems within minutes allows to focus on thereal problems.
I would not be writing these lines without the encouragement and support of my family throughout my life. Thank you for this. Lastly, thank you Geerte for your never-ending support and taking care of Lukas when I needed the time to finish this thesis.
