Reconfigurable Metamaterials in MRI — •Dennis Philipp1,2, Johannes Mueller1,2, and Matthias Guenther1,2 — 1Fraunhofer MEVIS, Bremen, Germany — 2University of Bremen, Bremen, Germany
Reconfigurable metamaterials (MTMs), operated in Tx and/or Rx during an MRI scan are an exciting new technology to leverage the full potential of MRI towards new imaging paradigms and potentially overcome existing limitations in terms of, e.g., SNR and imaging speed. They allow for on-demand RF field shaping during and/or between acquisitions and, thus, introduce new degrees of freedom into MRI. The potential advantages are, e.g., tailored local and spatio-temporal SNR enhancement for manifold applications.
Reconfigurable MTM prototypes are studied in simulations to infer a suitable geometry and parameter range of lumped elements for use in a 3T scanner. Prototypes are manufactured on rigid/flexible substrates and validated.
