| Short Biographical Sketch |
Prof. Dr. Marc KachelrießDr. Marc Kachelrieß was born in 1969 in Nürnberg, Germany. In 1989 he began to study physics with a focus on theoretical particle physics. His diploma thesis was entitled “Meson exchange currents in light nuclei”. He received his diploma at the Friedrich-Alexander-University of Erlangen-Nürnberg in 1995.
Then, Marc Kachelrieß started his dissertation at the Institute of Medical Physics (IMP) under the guidance of Prof. Willi A. Kalender. He developed reconstruction algorithms to reduce metal artifacts in x-ray computed tomography (CT). In parallel, Marc Kachelrieß introduced a new method that allows to generate motion-free images of the human heart using standard CT data. Thereby the clinical feasibility of retrospective electrocardiogram-correlated image reconstruction from CT data was proven. This method is now in world-wide use in clinical CT scanners. Marc Kachelrieß received his Ph.D. at the IMP in 1998.
Since then, he focuses on cardiac imaging and extended the approaches to future scanner generations. Other fields of his research work are image reconstruction of cone-beam CT data, iterative image reconstruction, image reconstruction algorithms in general. He is involved in developing algorithms for automatic exposure control (AEC) for CT, methods to reduce CT artifacts and patient dose reduction techniques. His work also includes the design and development of micro CT scanner hard- and software, micro CT pre- and postprocessing software and image quality optimization techniques.
In 2002 Marc Kachelrieß completed all post doctoral lecturing qualifications (habilitation) for Medical Physics and in 2005 he was appointed W2-Professor of Medical Imaging at the Friedrich-Alexander-University Erlangen-Nürnberg, Germany. On the basis of his university teaching position he lectures in medical imaging technology, physics and algorithms.
