Spatially selective excitation of an arbitrarily shaped three-dimensional target volume is demonstrated on a human MR scanner at 3T, accelerated by means of 8-channel parallel transmission. The good excitation fidelity and effective restoration of magnetization outside the volume of interest to the longitudinal direction allows for a reduction of the readout field of view in all three dimensions, resulting in an increase of resolution by a factor of two in all three directions while maintaining the measurement time.
