| Abstract | Introduction: Parallel transmission applies the principles of parallel imaging to RF transmission (1-3). Parallel RF transmission holds the promise of reducing dielectric resonance effects at high field strengths and enables control of RF distribution to optimize RF deposition. This enables optimization of the local specific energy absorption rate (SAR) (1-4). Parallel transmission may ultimately lead to a reduction of B1 inhomogeneities especially at the torso and spine at higher field strengths and to a shortening of total acquisition times. Up to now, parallel RF transmission has been primarily evaluated in simulation based studies and prototype MR systems (5;6) and not been used or fully tested on routinely used clinical high-field MR systems, which was the aim of the present study. |
