At 7T, T/R loop
coils have challenges in transmit B1+-field efficiency and
receive B1--field sensitivity in a spatial context, due
to the increased tissue dielectric/wavelength effect. Here we propose a revised T/R
loop coil schema which improves the B1-field non-uniformity at 7T.
The proposed modification may make the T/R loop coil construct yet more useful
at ultra-high fields.
