The research group High Field and Hybrid MR Imaging directed by Professor Harald H. Quick develops and evaluates new techniques and methods to broaden the spectrum of clinical applications of 7-Tesla ultrahigh-field magnetic resonance imaging (7T UHF MRI). Specifically, new multi-channel radiofrequency (RF) transmit/receive for 7T neuro and body MR imaging are simulated, designed, and evaluated. The ultimate aim is to assess the high signal-to-noise-ratio (SNR) inherent to UHF-MRI and to apply this to high resolution imaging in various diagnostic applications. The research groups of Prof. Harald Quick and Prof. Mark Ladd (DKFZ, Heidelberg) work in close cooperation to achieve this aim. Further active collaborations in the field of RF coil development exist with technical development partners in RF Technology Engineering (Prof. Klaus Solbach) and Electrical Engineering (Prof. Daniel Erni) of the University of Duisburg-Essen and with various clinical users of 7T UHF MRI from the University Hospital Essen. Field strength comparison studies serve to evaluate the clinical advantages and disadvantages of 7T UHF MRI when compared to 1.5T and 3T MRI. A further research focus is on safety aspects when imaging patients with passive and active implants.
Current research topics of Prof. Quick’s group in 7-Tesla ultrahigh-field MRI are the following.
