Tony Stöcker studied Geophysics at the Ruhr-University Bochum with focus on theoretical physics and mathematics. In 2000 he finished his PhD thesis about signal analysis and synthesis of tomographic data. In 2001 he joined the Department of Psychiatry and Psychotherapy of the University of Düsseldorf with Dr. Frank Schneider, with focus on methodological developments in functional Magnetic Resonance Imaging (MRI). In 2004 he changed to the Institute of Medical Imaging Physics at the Research Center Jülich with Dr. Jon Shah. His main focus was on the development of new MR imaging techniques, especially the theoretical and practical aspects of acquisitions tailored for structural and functional neuroimaging. Here, he was heading the MRI Sequence Development Team from 2007 until March 2012. His research interests are sequence development and optimization by means of MRI-simulation tailored for neuroscience applications, especially in the context of high-field MRI.
Tony Stöcker joined the DZNE in April 2012 as group leader of the MR Physics Research Group.
Areas of investigation/research focus
The research group MR Physics investigates novel medical imaging methods for preclinical biomarkers of neurodegenerative diseases. The early detection of neurodegenerative diseases using medical imaging techniques is a challenging and still unsolved task. Nevertheless, Magnetic Resonance Imaging (MRI) is the method of choice due to its inherently multi-modal character: MRI exploits many different biophysical and biochemical properties and provides quantitative information for brain tissue characterization. Furthermore, the noninvasive nature of MRI offers a great opportunity to perform large-scale longitudinal studies in patient groups as well as in healthy volunteers. However, it is very difficult to detect small changes in brain tissue, as they occur in neurodegeneration.
Our main focus is the MRI sequence development on a new state-of-the-art 7 Tesla human MRI scanner, probing for neurodegeneration with high sensitivity and resolution. The higher sensitivity of ultra-high magnetic field MRI brings the opportunity to detect subtle changes in brain function, structure, and metabolism as known to be present in early stages of neurodegenerative diseases. The accompanied challenges of ultra-high field MRI are an active and important area of basic physics research.
Another major aim is the support of high-throughput and high-quality neuroimaging at clinical 3 Tesla MRI scanners in the context of large-scale patient and population studies. It is intended to establish new fast and robust acquisition methods with high image quality for anatomical and diffusion MRI, MR parameter mapping, as well as functional and perfusion MRI. Due to their quantitative nature such methods are of ongoing interest with a future view to longitudinal image analysis and noninvasive MR-based computer aided diagnostics for neurodegeneration. In this context, fast MR image reconstruction algorithms and image post-processing routines need to be developed.
The MR Physics group also develops image acquisition methods on a state-of-the-art small animal MRI system. The system is equipped with a cryogenic probe and allows MR imaging at very high spatial and temporal resolution. These imaging techniques are suitable to detect neural plasticity, neurodegeneration, and regeneration in small animal disease models, which will provide new insights in cell biology and function and support translational research.
All projects are carried out in a multidisciplinary approach in close cooperation with the neuroscientists at the DZNE, as well as national and international collaborators, in order to find new ways for answering the urging questions on the processes of neurodegenerative diseases.
