dc.description.abstract | Inhomogeneous magnetic flux density under ultra-high field (UHF) magnetic resonance imaging (MRI) is mainly caused by a shortened RF wavelength propagating through a dielectric medium. Numerous studies on several types of traveling-wave antenna for UHF MRI are underway because of the potential alternative strategy of a large field of view with deeper penetration depth. In this study, a bilateral monopole antenna is proposed to improve RF transmission field (|B-1(+)|) uniformity at 297.2 MHz of 7 T. To investigate |B-1(+)| uniformity in this scenario, a bilateral monopole antenna is optimized by performing an electromagnetic simulation using a finite-difference time-domain method and improvements achieved using the optimized bilateral monopole antenna structure are discussed. | - |
