Binomial
water excitation is useful in low field MR system (<0.5T) for fat
suppression, but it is vulnerable to main magnetic field instability. Dynamic
magnetic field measurement is introduced in this method. The initial phase of
the RF pulses except the first RF pulse in the binomial RF train is modified
afterward in order to improve the performance of fat suppression. Result
shows that lipid signal was suppressed well while water signal is enhanced in
volunteer images.
