Abstract
In ultra-high field (UHF), body imaging suffers from B1 inhomogeneity due to shorter wavelength. A range of new RF coil designs has been proposed to overcome this problem. But, B1 inhomogeneity in the coronal plane still exists due to limited coverage. In this work, a novel design of an 8-channel top-hat dipole antenna with parallel transmission is proposed to improve B1+ homogeneity along Z-direction. B1 field distribution and SAR field were simulated in FDTD solver. Comparison with original dipole antenna array confirms the improved B1 homogeneity in proposed design.
