title = "Design considerations for dipole for head MRI at 10.5T",
abstract = "As the world's first 10.5T whole body human MRI scanner is ready for discoveries on new research frontiers, RF challenges need to be overcome to fully realize the benefits of the ultra-high MRI system. Dipole antennas were investigated with the Finite-Difference Time-Domain (FDTD) method. For best head MRI at 10.5T, results showed that dipole arrays should be long and conformal to the head geometry. A bottom ring connecting all dipole elements with adjustable capacitance can be helpful in improving RF homogeneity. RF and dielectric shielding, and dielectric pads around head may result in a dramatic rise of the Specific Absorption Rate (SAR) within head tissues.",
