Abstract

Magnetic Resonance Imaging (MRI) at higher magnetic fields (above 7 Tesla) suffers from radiofrequency field inhomogeneities that result in non-uniform transmission fields. The use of parallel transmission - transmitting on several antennas simultaneously, but with different waveforms can address this problem, but usually at a considerable cost due to the need to calibrate the RF pulses used on a per-subject basis. A recently developed concept - Universal Pulses, which have been calculated across a set of subjects - has been shown to produce uniform images with minimal setup times at 7 Tesla. Here we perform a feasibility study to see if the same approach is likely to bring benefits at 9.4 Tesla.
