We propose a setup to boost spatiotemporal encoding for MRI in the human brain using a conventional receiver array (32ch) and fast gradients (6100T/m/s). Moreover, we demonstrate that the operation frequency of a high-end gradient-amplifier can be increased to ultrasonic frequencies so to avoid unpleasant acoustic noise. By using this amplifier with 8 RF transmitters, 32 receivers and a 2-channel gradient coil, a light-weight setup is constructed for operation in a 7 Tesla MRI system. The setup is demonstrated for operation in the human brain showing good FLAIR data and no peripheral nerve stimulation at the slew rate of 6100T/m/s.
