b_282_160_16777215_00_images_institute_essen_ELHInstitut.jpgThe Erwin L. Hahn Institute for Magnetic Resonance Imaging is an interdisciplinary research institution for the study and application of magnetic resonance imaging (MRI) imaging in the neurosciences and in medical diagnostics and therapy. The inter-university institution was founded by the University of Duisburg-Essen and the Radboud University Nijmegen, Netherlands, in July 2005. In October 2006, the Erwin L. Hahn Institute had started its research at the historic industrial complex the UNESCO World Heritage Site Zeche Zollverein in the northeast of the city of Essen.


Research areas

• 7T whole-body high-field MRI, for example: whole-body angiography, abdominal and cardiac imaging
• 7T Neuroscience & fMRI
• Development of radio frequency (RF) systems and RF coils, e.g. Meander, stripline and loop coils
• Safety of RF coils and implants in high-field MRI
• Standardization of high-field MRI
• Sequences and methods for 1 channel, pTx and RF shimming eg TIAMO, 3D EPI, multi-echo EPI, Multiband EPI Imaging or Spokes and Zoomed Imaging
• Spectroscopy and chemical shift imaging, and X-nuclei e.g. 31P prostate spectroscopy or GABA spectroscopy
