Preliminary results of human head imaging at 9.4T are reported. To achieve safe and successful brain images at this new high-field bench mark, new RF technology and methods were required. Fortuitously the short Larmor wavelengths responsible for RF related artifacts also facilitate the B1 field phase and gain control required to compensate these artifacts. The multi-channel transceiver equipment, RF coils and interactive methods required to optimize image homogeneity and other criteria at 9.4T are presented. First of a kind 9.4T images so acquired are shown.
