Einladung zum Promotionsvortrag von Herrn Christian Hauke:
„Talbot-Lau X-ray Imaging“

Talbot-Lau X-ray imaging has already proven its promising benefit for medical diagnosis by various examinations carried out in laboratory environments on small animals and tissue samples. However, transferring the method from undisturbed laboratory environments to clinical practice, where the setup is exposed to hardly controllable influences, as well as transferring the method from small animals and tissue samples to human-sized objects is challenging.
Among other things, the method is extremely susceptible to vibrations and other external influences during the measurement process. Such influences can be prevented in a well-controllable laboratory environment, but not in clinical practice. In addition, scaling the method from small animals to human-like objects implies further difficulties, since this requires higher-energy X-ray spectra and thus an adjustment of the system.
In the upcoming talk, I present my findings, investigations, and developments necessary to overcome those challenges and present the first preclinical Talbot-Lau prototype which is capable of imaging human-like objects with a diagnostically relevant image quality even under clinical conditions and acceptable radiation exposure.
These results of research provide necessary and crucial improvements of Talbot-Lau X-ray imaging, which facilitate the method’s application in clinical practice. This is the prerequisite to use its diagnostic potential in future medical applications and thus extend medical imaging by a powerful modality.
