Goal
of this study was to expand the abilities of the Travelling Wave concept in
Ultra-Highfield MRI, to get an efficient body coil replacement in the future,
by using the advantage of a bigger diameter and an extended length of the
RF-shield. Promising results are shown by using the turnstile dipole antenna
as Tx and a phased array RF-coil for Rx. The highest SNR can be achieved
under Travelling Wave conditions because the B1-filling factor for phased array
RF-coil is much better.
