Spatially selective excitation of an arbitrary three-dimensional target pattern is demonstrated in vivo in the head of a volunteer at 3T for the first time. A parallel transmit system with eight independent RF channels is used in combination with a slew-optimized single-shot 3D shells trajectory. The good excitation fidelity allows for the reduction of the field of view below the extent of the head and consequently for a shorter acquisition with higher spatial resolution.
