The 16-element antisymmetric dipole array fits with the same dimensions as
an 8-element straight dipole array. Anatomical T1-weighted images of the pig heart were acquired on a fresh cadaver (15min postmortem) at
high spatial-resolution (0.5×0.5×4mm3).
Figure 5. Slices of the short-axis
view stack of the pig heart acquired post-mortem. The right panels show
increased image slices marked red on the left panel. The LGE in the
post-infarction scar is observed in the septal and anterior wall (arrows).
Sufficient $$${B_1^+}$$$ field penetration and homogeneity without destructive interferences are
achieved in the whole heart in both anterior-posterior and basal-apical
directions.

of the mono-surface antisymmetric 16-element dipole
antenna array with element dimensions,
paring channels, and channel numbers with every two neighboring dipoles to
form 8Tx-channels for the pTx system (8Tx/16Rx). (b)

loaded with a dedicated pig thorax phantom. (c)-(d)
Prototypes of the dedicated pig thorax phantom and the antisymmetric dipole antenna array.
