This work systematically investigates the factors that
could pose negative influence on the transmit pulse
performance at 9.4 tesla. These factors are B1 mapping
inaccuracy, B0 inhomogeneity, actual RF and gradient
pulse deviations, among which B1 mapping inaccuracy and
actual RF pulse deviations are deemed as the major
influence factor. Comparative measurements with and
without consideration of these factors during the pulse
design process, including one in vivo experiment, are
performed.
