The “Loopole” Antenna: A Hybrid Coil Combining Loop and Electric Dipole Properties for Ultra-High-Field MRI

Table 1

Simulated and experimental and SNR values at the central voxel in the body-sized phantom. Both in simulations and experiments, the loopole array demonstrates significant efficiency and SNR boosts compared to the loop array and marginal improvements compared to the dipole array.
