Abstract

A method is provided for modified gradient timing in a Magnetic Resonance (MR) imaging system. The method includes generating radio frequency (RF) excitation pulses in a volume of patient anatomy to provide subsequent acquisition of associated RF echo data and generating a sequence of gradient waveforms on a static magnetic field in three directions each orthogonal to each other for slice selection, phase encoding and readout RF data acquisition in the volume of patient anatomy. The method also includes receiving, by a controller, an indication of the sequence of gradient waveforms to be applied to a plurality of gradient coils and modifying, via the controller, the sequence of gradient waveforms to be applied to the plurality of gradient coils based on one or more parameters to produce a sequence of modified gradient waveforms. The method further includes providing the sequence of modified gradient waveforms to the plurality of gradient coils.
