1. A method for shaping an RF pulse for use with a magnetic resonance imaging (MRI) system, the method comprising:
shaping a radio-frequency (RF) pulse for use with an MRI system that uses an RF coil, wherein said RF pulse is shaped to reduce changes in B1 amplitude and in an off-resonance effect with respect to Larmor frequency as a function of distance from said RF coil.
