The human spine is one of the most frequently imaged
body parts in clinical MRI. The imaging performance can
be restrained by SAR restriction, B1+-inhomogeneities or
insufficient B1+-peak values. In the following an
optimized local transmit antenna structure for spine
imaging is presented which offers reduced SAR values,
improved B1+-inhomogeneity and reduced power
requirements in comparison to examination with the body
coil antenna. Following EM-simulations, the antenna
structure was manufactured and successfully integrated,
showing significant potential for future work in 3T MRI
imaging with local transmit coils.
