2020 is the year of X-rays - 125 years ago Wilhelm Conrad Röntgen discovered a "new type of radiation". In the Welt-der-Physik podcast entitled "X-ray radiation", Franz Pfeiffer, Professor of Biomedical Imaging at TUM and Director of the Munich School of BioEngineering, talks about Röntgen's discovery and explains the physical principle behind X-ray imaging

The potential of X-rays for medicine was recognized early on. In the course of time, the radiation exposure has been reduced and the resolution of X-ray images has been significantly improved, but modern X-ray machines hardly differ from the first models. In fact, not that much has changed in the last 50-100 years, purely in terms of the physical principle, ”said Franz Pfeiffer in the podcast.

But X-rays contain far more information than is used in everyday medical practice today. The podcast also explains how X-rays can be used in new methods for medical imaging - for example the dark field method that was developed by Franz Pfeiffer.
