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

Figure 8

Experimental maps clearly show the asymmetric behavior of the loopole array. A small deviation in is observed in the loop array between the two orientations. In the optimal orientation, the loopole array demonstrated a 40% boost in central when compared to the loop array and a 5% boost when compared to the dipole array.
