Abstract:
In this work the usage of a composite right/lefthanded (CRLH) metamaterial transmission line resonator as a transmit/receive coil for 7 Tesla magnetic resonance imaging (MRI) is investigated. On the basis of zeroth-order resonant antennas (ZORAs) a zeroth-order resonant coil (ZORC) was designed. Due to a constant current distribution along the element, a homogenous magnetic field is achieved in a larger area compared to a conventional microstrip transmission line(MTL) element. Numerical and experimental results are presented. Keywords— metamaterial, CRLH, MRI, ZORA, ZORC
