Improvements in radio-frequency transmission for ultra-high field magnetic resonance imaging through a bilateral monopole antenna

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 alter...
