Zusammenfassung
Whole body imaging at 3T and above may be disturbed by B1 field inhomogeneity caused by wave propagation effects. Simulations [1] have shown that RF shimming techniques can compensate such inhomogeneities. Furthermore, the acceleration of 2/3D spatially selective excitations enables new and/or improved technical features like zoom imaging, navigators or arterial spin labeling and other advanced parallel transmission techniques [2–4]. This paper describes the first fully integrated MRI prototype system based on a standard commercial 3T Philips MRI scanner, which features a fully integrated multi-element body coil…
