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.
