Abstract:
1. A method, of emitting radio frequency (RF) pulses into an object during magnetic resonance imaging (MRI), comprising: emitting a first RF pulse into the object with a first RF excitation coil element, wherein the first RF pulse comprises a first RF waveform; emitting a second RF pulse into the object with a second RF excitation coil element, wherein the second RF pulse comprises a second RF waveform that is time shifted relative to the first RF waveform by 2nπ/γG, where G is a gradient strength of a slice-select gradient, γ is a gyromagnetic ratio in units of radians per unit gradient strength, and n is an integer; and emitting a third RF pulse into the object with a third RF excitation coil element, wherein the third RF pulse comprises a third RF waveform that is time shifted relative to the first RF waveform by −2nπ/γG.
